I completely understand what you are going through. It's so hard to let down those protective walls you've spent a lifetime building up. And what a hard road it is to even knock a chip off that wall! But it can be done (so they say).

Dealing with childhood trauma is very delicate work. I wonder if your T lacks experience in this area. My guess is CT is something your T has just not practiced in, based on the questions she asked. I will bet she is right on one thing though -- childhood trauma is the root of the problem. CT can cause a lot of maladaptive behaviors in adulthood. At any rate, you might want to ask your T what her experience level is in dealing with CT.

Also, it may ease your mind to outright ask your T if she is planning on terminating you. I have these same fears even after 1 year with my current T. She reassures me all the time that she will always be here for me, and so on. But my mind likes to freak me out and tell me otherwise once in a while. So I now just straight up ask her instead of letting my fears spiral out of control. And it's always me reading way too much into some little comment T made.
