I agree that your T is not being professional. You are the client. As the therapist his job is create a secure, reliable place for you. That is T's job and not yours. Please give yourself some slack on that. He is wrong to act this way. HIS job is to maintain the professional relationship with strong boundaries and to do what he says he's going to do. He messed up.

You are doing your part but you can't do his part too and make him more reliable.

I am sorry you are going through this. It is tough when we have these days, periods of hurt.
