Sometimes the most difficult part oftrauma is being able to know the truth ourselves.
When I was doing my trauma work last year, I was always doubting my own truth.
My T said that my pain was very real, and who would bring themselves that much pain by thinking thing up. He taught me HOW to trust MY body and MY flashbacks.

A part of trauma is the denial stage! I dont think your T is a trauma expert from the way it sounds. Mine is. So I say you should go with your body and feelings. In order to survive great pain, the mind will try to tell itself the event never happened.

big hugs to you!
