It's just transference. One time I totally responded to T as though my mother was sitting in that chair. We were talking about SI and I literally yelled at him. I yelled, "I don't wanna %#@&#! talk about this with you because you don't %#@&#! give %#@&#! anyway!!" (Of course this was not true of T at all-- in fact he cared very much. I was responding to him as though he were someone else).

Also, if it was a psychotic break, you wouldn't really have the awareness to sit and ponder if it was a psychotic break. You would completely believe that T was this other person and have no awareness that she is not.

Use this as a valuable transference experience, especially since you talk about how angry you get at your T-- I think you mentioned that you hate her. It sounds like you are doing some very good work there.
