No, I've never had that, but she's trying to let you know that her diagnosis is correct based on factual knowledge. As soon as that is all settled, she will likely be more personally responsive to you; at least, I hope so.

Therapy is a personal relationship in some ways. It's help to see things in a better or clearer way. And it's designed to strengthen your understanding of yourself. Those are really her objectives, in my view.

Take care of yourself in therapy and listen but also say what you really feel. That's the best way to clarify what's happening. For example, ask "why do you feel that it's necessary to give statistics about what I'm feeling? Are you trying to make certain that your diagnosis is correct 100%? Is this an effort to strengthen my belief about the illness that I have and how I am to manage it?" Nothing is wrong with approaching her in that manner. She'll tell you the truth, I think.

Take care of yourself.
