I know it's hard to do, but try to remember that her feelings on this do not matter: yours do. She should be able to understand your fear and respect it, without making it about her and being offended (I'm not sure if that's happening or not).

I have been dealing with this with my T for a long while. Fear is a hard nut to crack! It's really been empowering for me to find the words to be able to tell him to back up, move clear across the room, etc. He is always 100% willing to acquiesce and will do things like avoid eye contact, warn me before he moves, etc. My sense of safety has never been respected before so this has been huge for me.

It helped a lot when I stopped trying to "get over" my fear of him and instead focused on working through it with him. It's like I thought my fear was getting in the way of us doing therapy work--but this IS the therapy work.
