Stringcheese... I understand it must be really upsetting... I am sure you are a wonderful person and its very unprofessional to say you treat trauma and then freak out when someone has a flashback...

I personally have been so dissociative I have lost time... and I so hate the feeling of not knowing what i did or was doing even if its only for 15 minutes... my take on this is that you brought up some issues for T that she isn't willing or able to handle..

A professional T would have sought supervision for something they don't know how to handle and then discuss with you if they feel your case is too difficult for them to treat and then help you find a new T who would be better suited... I'm so sorry you are going through all of this...
