It seems to me that your Ts actions may have been a trigger for you to re-experience rejection and abandonment, perhaps powerlessness. I had an experience that my ex- Ts words triggered me, and I always felt she should have given some acknowledgement - really I wanted her to apologise or at the least support me in focusing on the emotions I felt, really I think these emotions were the key to my issues. I don't know how you and your T can get passed this, I'd be interested to hear if you do and how you manage it. There were a number of reasons why I quit that T, but this was one of them. I discussed the triggering briefly with my new T, and I just know that it would/ will be handled really differently if it happens with her. I too felt that my therapy was traumatising. I tried and tried and tried to stay with it.
