What Is Trauma?
Understanding Trauma: Big T, Little T, and How Your Nervous System Holds It
When people hear the word trauma, they often picture extreme events—war, abuse, natural disasters, or serious accidents. And yes, those experiences can absolutely be traumatic. But this narrow view leaves many people asking:
“If nothing that extreme happened to me, why do I still feel this way?”
Here’s the thing: trauma isn’t defined by what happened—it’s defined by how your nervous system experienced and stored it (van der Kolk, 2014).
Trauma Is About Impact, Not Intent
Two people can go through the same event, and only one may feel traumatized. That doesn’t mean anyone is “weaker” or “too sensitive.” Trauma is subjective. Your nervous system, past experiences, age, support, and resources all shape how an event affects you.
What matters most is how safe, supported, and resourced you felt at the time—not whether someone else thinks it “should” have been traumatic.
Big T Trauma
Big T trauma refers to events widely recognized as traumatic because they involve clear threats to life, bodily integrity, or safety.
Examples include:
Physical, sexual, or emotional abuse
Domestic violence
Serious accidents or medical trauma
Natural disasters
Combat or war exposure
Sudden loss of a loved one
Assault or violent crime
Big T trauma often overwhelms the nervous system and can lead to symptoms like flashbacks, nightmares, hypervigilance, emotional numbing, anxiety, or panic (Ogden, Minton, & Pain, 2006).
Because society recognizes these experiences as trauma, people are usually more likely to seek support for them.
Little T Trauma
Little T trauma might not involve obvious danger, but it can still be overwhelming—especially when it happens repeatedly or during sensitive developmental stages.
Examples include:
Chronic criticism, shaming, or emotional invalidation
Emotionally unavailable or unpredictable caregivers
Bullying or social exclusion
Feeling responsible for a parent’s emotions
Repeated rejection or abandonment
Living in a high-conflict or unsafe home
Medical procedures without comfort or explanation
Being told your feelings were “too much” or “not important”
Alone, these experiences may seem small. Over time, though, they can shape core beliefs such as:
“I’m not good enough.”
“My needs don’t matter.”
“I have to stay on guard.”
“I’m unsafe being myself” (Levine, 2010).
Many people minimize Little T trauma because they were never taught to recognize it—but it can profoundly affect self-worth, relationships, emotional regulation, and safety in the world.
Why You Might Not Recognize Your Trauma
You might not identify with the word trauma if you’ve thought:
“Nothing terrible happened to me”
“Others had it worse”
“I should be grateful”
“I just had to keep functioning”
Survival often looks like competence, independence, or emotional control. Many people with trauma histories are high-functioning and successful outwardly, while internally feeling anxious, disconnected, exhausted, or numb.
Signs your nervous system may still carry trauma include:
Chronic anxiety or depression
Emotional avoidance or shutdown
People-pleasing or perfectionism
Difficulty trusting others
Intense self-criticism
Feeling stuck despite insight
These aren’t character flaws—they’re the residue of unresolved trauma (van der Kolk, 2014).
A Gentle Invitation
If you see pieces of your own story here—especially experiences you never thought of as trauma—you don’t have to sort through it alone.
I offer a free consultation call to explore whether trauma-informed therapy could support you. There’s no obligation—just a safe space to ask questions, be heard, and consider your next steps.
Healing isn’t about what “should” have hurt. It’s about honoring what actually did—and helping your nervous system finally feel safe enough to let go.
