It is sad to see how T's reaction is creating a barrier between the two of you. And now, you feel you need to edit or censor what you want to say to her (e.g. your concern about her).

I don't see why, with a good T, a client should not be able to talk about their reactions, feelings or concerns about their T. It does not mean she has to disclose anything but I think it is very important to explore your feelings about what is happening with her. Imo, this should be part of the therapy work. Why? Because it is in the space. How can ignoring (or pretending not to see) what is in the space, be therapeutic?
