I'm really sorry you're dealing with this. I know you said you've each met with the T individually and are now set to meet together. I wonder if you'd be able to talk about these concerns with the therapist individually before meeting (or maybe email them, something like that?) to get some sort of reassurance that she won't just treat this like a miscommunication?

Are you still in touch with the one T you saw periodically who specialized in disabilities? Was that Visa maybe? I'm wondering whether she could advise you on whether this is a good idea, some suggestions on how to approach it in the joint session(s), etc. I feel that maybe you ended on a bad note with her, so perhaps not.

I don't know how it works where you are but I'd be thinking more employment tribunal than therapist!
