Understanding Trauma: Signs, Symptoms, Types, and Treatment in San Diego
What is Trauma, PTSD and C-PTSD?
Have you ever wondered whether you’ve experienced trauma?
Maybe something happened to you years ago that you still think about frequently. Perhaps certain situations trigger an emotional or physical reaction that seems bigger than the situation itself. Or maybe you experience anxiety, panic attacks, depression, nightmares, or difficulty trusting others and wonder whether your past could be contributing to what you’re experiencing today.
You may even find yourself asking:
“Was what happened to me really traumatic?”
“Why am I still affected by something that happened so long ago?”
“How do I know if I have PTSD?”
These are important questions, and you're not alone in asking them.
Trauma can affect people in many different ways. Not everyone who experiences a traumatic event develops PTSD, and there isn't one “right” way to respond to trauma.
Understanding what trauma is, how it can affect you, and what treatment options are available can be an important first step toward healing.
What Is Trauma?
Trauma is an experience—or series of experiences—that is deeply distressing, frightening, or overwhelming and can have lasting effects on the way a person functions emotionally, physically, socially, or psychologically.
Trauma can happen when we experience something threatening or harmful ourselves. It can also occur when we witness something traumatic happening to someone else or learn that something traumatic happened to someone close to us.
One way I explain trauma to my clients is this:
Trauma isn't simply about what happened to you. It's also about what happened inside of you as a result of what you experienced.
Traumatic experiences can affect the way we understand ourselves, other people, and the world around us. They can influence our thoughts, emotions, relationships, behaviors, and even the way our nervous system responds to perceived danger.
Psychiatrist and trauma expert Bessel van der Kolk, author of The Body Keeps the Score, describes trauma as something that can overwhelm the nervous system and alter the way we process and recall memories.
This helps explain why someone can intellectually understand that an experience happened in the past while their body continues to respond as though the danger is happening right now.
You may know, “I'm safe now,” while another part of you is still saying, “I'm not safe.”
That disconnect can be incredibly confusing.
What Can Cause Trauma?
Trauma doesn't look the same for everyone, and traumatic experiences can take many different forms.
Some examples of potentially traumatic experiences include:
Childhood physical, sexual, or emotional abuse
Childhood neglect
Domestic or intimate partner violence
Sexual assault or rape
Physical assault
Motor vehicle accidents
Natural disasters
Fires and serious accidents
Serious medical conditions or medical procedures
Cancer diagnoses and other life-threatening illnesses
Serious injuries
Community or school violence
War or military-related trauma
Torture
Human trafficking
Witnessing a homicide or suicide
The sudden or violent death of someone you love
Betrayal or profound relational trauma
Bullying, humiliation, or severe psychological abuse
Significant losses or separations
Historical, collective, or intergenerational trauma
Trauma can also occur in less obvious ways.
For example, someone may grow up in a household where they were constantly criticized, emotionally neglected, or made to feel unsafe. There may not have been one single event that they can point to and say, “That's when everything changed.”
Instead, the impact may have accumulated over time.
This is one reason that understanding trauma requires looking at the whole person and the context of their experiences, rather than simply checking whether someone experienced one particular event.
What Does the DSM-5 Consider a Traumatic Event?
The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) defines the trauma exposure required for a diagnosis of PTSD as exposure to actual or threatened death, serious injury, or sexual violence through one or more of the following:
Directly experiencing the traumatic event
Witnessing the event in person as it occurred to someone else
Learning that a traumatic event happened to a close family member or close friend, when the death or threat was violent or accidental
Experiencing repeated or extreme exposure to details of traumatic events, typically as part of one's work
The DSM-5-TR also makes an important distinction: exposure through television, movies, photographs, or electronic media generally does not meet this criterion unless that exposure is work-related.
It's also important to remember that experiencing a traumatic event does not automatically mean that someone has PTSD.
People respond to trauma differently.
How Does Trauma Affect Us?
Some people experience relatively brief reactions following a traumatic event and gradually return to their previous level of functioning.
Others experience symptoms that persist for months or years.
Some people don't experience significant symptoms until much later.
You might feel fine immediately after an event and then begin experiencing anxiety, nightmares, panic attacks, or emotional distress months—or even years—later.
There is no single “correct” way to respond to trauma.
Your response is influenced by many factors, including the nature of the experience, your age and developmental stage, your previous experiences, your support system, your sense of safety, and many other individual circumstances.
And perhaps most importantly:
Having a strong reaction to trauma doesn't mean you're weak.
Your symptoms may actually be your mind and body attempting to protect you.
What Are the Symptoms of Trauma and PTSD?
PTSD symptoms are generally grouped into four categories:
1. Re-Experiencing
You may feel as though the traumatic experience is happening again.
This can include:
Intrusive thoughts or memories
Nightmares
Flashbacks
Emotional distress when reminded of the trauma
Physical reactions to reminders of the trauma
2. Avoidance
You may find yourself going out of your way to avoid anything that reminds you of what happened.
This might include avoiding:
Certain people
Places
Conversations
Activities
Memories
Thoughts or feelings associated with the trauma
Avoidance can feel helpful in the short term because it temporarily reduces distress. Unfortunately, extensive avoidance can make it harder to process what happened over time.
3. Changes in Thoughts and Mood
Trauma can influence the way you think about yourself, other people, and the world.
You may experience:
Negative beliefs about yourself
Shame or guilt
Difficulty trusting others
Emotional numbness
Feeling disconnected from yourself or others
Depression
Loss of interest in activities
Difficulty experiencing positive emotions
Persistent negative emotions
You might find yourself thinking:
“It was my fault.”
“I'm not safe.”
“I can't trust anyone.”
“Something bad is always going to happen.”
These beliefs can become deeply ingrained following trauma.
4. Hyperarousal and Hyperreactivity
Your nervous system may remain on high alert, as though it's constantly scanning for danger.
This can look like:
Anxiety
Panic attacks
Hypervigilance
Being easily startled
Irritability or anger
Difficulty sleeping
Difficulty concentrating
Feeling constantly “on edge”
Physical tension
You may feel like you're waiting for the other shoe to drop.
Even when everything around you appears to be okay, your body may not feel safe.
What is Complex or Developmental Trauma?
Some people experience multiple, chronic, or prolonged traumatic experiences, particularly during childhood.
This is often referred to as complex trauma or developmental trauma.
For example, a child who grows up experiencing ongoing abuse, neglect, domestic violence, or an unpredictable caregiving environment may not have one isolated traumatic memory. Instead, their experiences may have shaped the way they learned to understand relationships, safety, themselves, and the world.
When trauma occurs during childhood, it can affect development in particularly significant ways because children are still learning how to regulate emotions, form relationships, understand themselves, and make sense of their surroundings.
You may have learned things like:
“I have to take care of everyone else.”
“My needs don't matter.”
“I can't trust people.”
“I have to stay alert because something bad could happen.”
“There's something wrong with me.”
These beliefs may have once helped you adapt to your environment.
But what helped you survive then may not necessarily serve you now.
What Are Some Signs of Complex Trauma?
People who have experienced chronic or developmental trauma may struggle with:
Difficulty regulating emotions
Feeling easily triggered
Anxiety or panic
Depression
Dissociation or feeling disconnected from yourself
Chronic muscle tension or physical distress
Difficulty trusting others
Relationship difficulties
Fear of abandonment
Difficulty setting boundaries
Shame or self-blame
Negative beliefs about yourself
Feeling responsible for other people's emotions
Difficulty concentrating or functioning at work or school
Feeling unsafe even when there is no immediate danger
It's important to note that Complex PTSD (C-PTSD) is distinct from PTSD, although the two conditions overlap considerably.
C-PTSD is recognized in the World Health Organization's ICD-11 and includes the core symptoms of PTSD along with additional difficulties involving emotional regulation, self-concept, and relationships.
Regardless of the terminology used, the important thing is understanding how your experiences have affected you and identifying the support that can help.
Trauma Isn't Always Obvious
One of the most important things I want people to understand about trauma is that you don't have to look “traumatized” to have experienced trauma.
You may be highly successful.
You may have a good career.
You may have a loving family.
You may look like you have everything together.
And you may still struggle internally.
Sometimes trauma looks like anxiety.
Sometimes it looks like perfectionism.
Sometimes it looks like people-pleasing.
Sometimes it looks like anger.
Sometimes it looks like shutting down.
Sometimes it looks like panic attacks that seem to come out of nowhere.
Sometimes it looks like feeling disconnected from yourself or your emotions.
And sometimes it looks like simply feeling exhausted from trying so hard to keep everything together.
What Are the Treatment Options for Trauma, PTSD, and Complex Trauma?
The good news is that trauma is treatable.
There are several evidence-based therapeutic approaches that can help people process traumatic experiences, develop healthier coping strategies, and reduce trauma-related symptoms.
Some approaches include:
Attachment-based approaches
Cognitive Behavioral Therapy (CBT)
Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), particularly for children and adolescents
Cognitive Processing Therapy (CPT)
Eye Movement Desensitization and Reprocessing (EMDR)
Dialectical Behavior Therapy (DBT)
Group Therapy for Trauma
Internal Family Systems (IFS)
Mindfulness-Based Stress Reduction
Narrative Therapy
Polyvagal Theory
Prolonged Exposure (PE)
Psychodynamic Therapy
Mindfulness-based interventions
Somatic Experiencing (SE) or other somatic and body-based approaches
There isn't one therapy that is perfect for everyone.
Your treatment should take into consideration your symptoms, goals, preferences, history, and readiness.
For someone who has experienced complex or developmental trauma, treatment may involve integrating several approaches over time.
For example, therapy may initially focus on building safety, developing coping skills, learning emotional regulation, and strengthening your ability to stay grounded before moving into deeper trauma processing.
Healing doesn't have to happen all at once.
How Can EMDR Help With Trauma?
One of the trauma-focused approaches I use in my practice is Eye Movement Desensitization and Reprocessing (EMDR).
EMDR is an evidence-based psychotherapy approach that can help people process distressing memories and experiences so that they become less emotionally overwhelming.
The goal isn't to erase what happened.
You can't—and don't need to—change your history.
Instead, EMDR can help change the way the memory is stored and experienced so that you can remember what happened without feeling as though you're back in the middle of it.
You may still remember the experience.
But eventually, the memory can become:
“That happened to me.” rather than: “It's happening to me.”
For people struggling with trauma-related anxiety, panic, shame, or distressing memories, this shift can be incredibly meaningful.
You Don't Have to Figure Out Your Trauma Alone
If you've been wondering whether your past experiences are contributing to what you're experiencing today, you don't have to figure it out by yourself.
Therapy can provide a safe place to slow down, understand what's happening, learn why your mind and body respond the way they do, and develop tools to help you feel more grounded and in control.

FAQs About Trauma and PTSD
How do I know if I have trauma?
Trauma can show up in many different ways, and you don't necessarily have to experience every symptom to have been affected by a traumatic experience. Anxiety, panic attacks, nightmares, intrusive memories, avoidance, emotional numbness, hypervigilance, difficulty trusting others, and negative beliefs about yourself can all be signs that past experiences are continuing to affect you. A qualified mental health professional can help you better understand your symptoms and determine whether trauma may be contributing to them.
Can you have trauma without having PTSD?
Yes. Experiencing a traumatic event does not automatically mean that you will develop PTSD. People respond to traumatic experiences differently. Some people experience temporary distress and gradually recover, while others develop symptoms that persist and interfere with their daily lives. You can also experience the effects of trauma without meeting the diagnostic criteria for PTSD or you may meet criteria for another mental health condition such as depression or generalized anxiety.
Can childhood experiences cause trauma in adulthood?
Yes. Experiences during childhood can continue to influence your emotional and psychological well-being well into adulthood. Childhood abuse, neglect, domestic violence, unstable caregiving, and other adverse experiences can affect how you understand yourself, relationships, safety, and the world around you. Sometimes the connection between childhood experiences and current struggles doesn't become apparent until adulthood.
Can trauma cause panic attacks?
Trauma can contribute to panic attacks and other anxiety symptoms. When your nervous system has learned to remain on alert for danger, it may respond strongly to situations, sensations, or reminders that feel threatening—even when you aren't consciously aware of what triggered the reaction. Trauma therapy can help you understand these responses and develop healthier ways of managing them.
What is the difference between PTSD and complex trauma?
PTSD generally develops following exposure to a traumatic event and involves symptoms such as re-experiencing, avoidance, negative changes in thoughts and mood, and changes in arousal and reactivity. Complex trauma typically refers to repeated or prolonged traumatic experiences, often beginning during childhood or occurring within relationships or caregiving environments. Complex PTSD (C-PTSD), which is recognized in the ICD-11, includes the core symptoms of PTSD along with difficulties related to emotional regulation, self-concept, and relationships.
Can trauma symptoms appear years after an event?
Yes. Some people experience trauma symptoms immediately, while others may not notice significant symptoms until months or even years later. Changes in your circumstances, relationships, stress levels, or other life experiences can sometimes bring previously manageable trauma responses to the surface.
What is EMDR therapy, and can it help with trauma?
EMDR (Eye Movement Desensitization and Reprocessing) is an evidence-based psychotherapy approach used to help people process distressing or traumatic experiences. Rather than erasing memories, EMDR aims to help you process them in a way that reduces their emotional intensity and the distress they continue to cause. EMDR can be an effective treatment for PTSD and other trauma-related difficulties.
Do I have to talk about my trauma in therapy?
Not necessarily, especially when you're first beginning therapy. Trauma-informed therapy recognizes the importance of safety, trust, and readiness. Your therapist should work collaboratively with you and respect your pace. Developing coping and emotional regulation skills may be an important first step before processing traumatic memories.
How long does trauma therapy take?
There isn't one timeline that applies to everyone. The length of trauma therapy depends on factors such as the type and complexity of the experiences you've been through, your current symptoms, your goals, your support system, and the therapeutic approach being used. Some people may benefit from a relatively short course of treatment, while others may need longer-term therapy, particularly when working through complex or developmental trauma.
Where can I find trauma therapy in Chula Vista or San Diego?
If you're looking for a trauma therapist in Chula Vista or San Diego, consider looking for someone who has specialized training and experience working with trauma and PTSD. I provide trauma-informed in-person therapy in Chula Vista and online counseling for California residents.
