Thanks to everyone who has shared their stories and pain and has contributed to this thread. I threatened my previous traumatizing T with a formal complaint which I didn't have any intention of actually doing , I just wanted her responses and reflection ( which I got ). I went into EMDR and the first thing we worked on was the T's retraumatisation. I did well with EMDR , but now this supervisor has pulled the same stunt. I have less trauma but also less tolerance for this now , so I may go a bit further with a complaint. They really need to take it on board the damage they do , that they can't sit in ivory towers being egotistical and thinking they know best and messing about with peoples trauma. We will see what transpires , and they may have second thoughts before they do it to other people.
