Do you think that you could ask your T for more information about what therapy for CPTSD is supposed to accomplish, and how? Do you feel that a better cognitive understanding might help as you try to go through the therapy as well as continue with your adult life?
As I have said before, the "corrective relationship" did not work for me. Except, perhaps, that close to 2 years after the relationship ruptured without repair, I see that as the T's issue and failure. And although I seriously doubted my ability to have "corrective" relationships with anybody, especially other females, that anxiety is improving as I have lucked into meeting some people and some friendships, I think, through some support groups.
Best of luck to you!

I'd like to think that maybe this stuff could work for some folks, because my life had been pretty miserable and I wouldn't wish it on my worst enemy -- except if going through it could help my worst enemy, somehow, in a way that they wanted or at least were glad to have had after they got through it. But that means somebody has to get through it, and I don't think there are any guarantees about that, currently. Hence, maybe it would help if therapists provided more information? Or maybe not, just a thought.
