I can't believe your T thinks this for a moment. You say you believe your T "hints" at this. Well, that's the kind of "interpretation" of ambiguous statements that could say more about your feelings toward yourself than about your T's opinions.

I entirely agree with Marie and Rainbow: trauma is something that usually happens to a person early in life, inflicted by one or more others. Trauma can happen in adult life too but only in the kinds of circumstances that occur involuntarily: war, crime, accidents, that kind of thing.

How you react in and out of therapy now are results of either early trauma or your PTSD. You'd do best to clear this up with your T. Take care!
