I'm sorry sweety that you are going through all this, and yes I can relate, but I can relate to a bunch of other things too.
Can you ask your T if he has any trauma experience? He might get it then. I'd still be open with them and see where it goes.
The best thing that you can be with your T is like totally honest.
I saw my pdoc for the first time, or should I say No_one did, and he straight up blurted it out in a freaked out kind of way....a little embarrassing like. But it's been outed.
But it helped me more by understanding this coping method that our brains have adopted.
I wish you the best hun, luv!
