What is trauma and do I have it?

Answered by Dr. Nitnem Singh Sodhi · Mental Health Counsellor, Neuropsychologist & Psychotherapist · Updated 2026-06-08

Short answer

Trauma is not the event itself; it is the unresolved nervous-system imprint an overwhelming event leaves behind. You may have it if certain triggers still produce disproportionate reactions years later. Effective treatments (EMDR, trauma-focused CBT, somatic work) exist and work.

The clinical definition

Trauma is the residue an overwhelming experience leaves in the nervous system when the experience could not be fully processed at the time. The event is not the trauma; the unresolved imprint is. This is why two people can go through the same event and only one carries it forward.

Big-T and small-t

Big-T trauma is what most people picture: assault, accident, disaster, war, abuse. Small-t trauma is the cumulative kind: chronic invalidation in childhood, emotional neglect, sustained bullying, an unpredictable parent. Small-t is often more disruptive in adult functioning because it shaped the baseline, not just a memory.

Signs you may be carrying it

Disproportionate reactions to specific triggers (a tone of voice, a smell, being interrupted). Emotional flooding or shutdown that feels older than the current situation. Difficulty trusting, difficulty resting, hyper-vigilance in safe spaces. Recurrent nightmares. A sense that some part of you is still 'back there'.

What treatment looks like

Modern trauma work is not endless retelling of the story. Approaches like EMDR, trauma-focused CBT, and somatic experiencing help the nervous system finish processing what it could not finish at the time. It is often faster than people expect — sometimes 8 to 20 focused sessions — and the change is durable.
