Sounds like she's making a bunch of rookie mistakes. Understandable, but you aren't obligated to be her training tool if you're not comfortable. If it was just the Dx question, I'd cut some slack and recommend talking it out. But you've listed a number of ways she just isn't clicking for you, and hey, you're in a vulnerable place and feeling a lot of pain. You don't need a therapist who can't catch your rhythm and make you feel safe and heard.

If you have the option to change, I say PUNT! Let her train with someone with whom she connects. You need effective treatment, and that doesn't come with a T who is consistently rubbing you the wrong way or making you feel upset or confused. Life's too short; move on.
