I agree that Internal Family Systems may be a good fit for you. From what I understand of IFS, the goal is to strengthen your own internal "good enough parent" (as opposed to seeking it from others). YOU become the resource you need! I think I would work well with it too.

I know you're angry at ex-Dr. T, but I see a lot of positive changes in you since you started working with him. I think the lessons you took from your work with Ex-MC, and now Ex-Dr.T, have brought you to the place you are RIGHT NOW... which is exactly where you need to be.

My current T is like ex-Dr.T. The work was very painful (he was the first to tell me that I am "histrionic"), but it was actually very helpful to me in the long run. It hurt like a mofo when it happened, but I grew from it.
