yang,
first of all

i am so so sorry this happened and that you are in such pain over it.
i honestly have no wise words on this. I think something like this would totally affect the trust i would have in a space that is supposed to be safe. i couldn't work like that.
is there a way for you to have your therapist block access of your information to other providers - deny permission? (in writing)
the only other thing i can think of IS to keep taking about it because it clearly is in the way of any other work you are trying to do - and figure out a way to move forward.
