For anyone who might read this later, I didn't tell her. I don't think she would have been interested, but it turns out I didn't need to dig too deep anyway. She self disclosed some information which was more or less the reason I wasn't sure if I wanted to work with her or trust her. Knowing the truth about it makes it much easier. I also could have figured out the answer if I had googled her apparently (she said "you didn't google me did you?" and I said only far enough to read reviews, she said "if you had googled more you'd know I'm xyz on this issue professionally and I'll tell you I'm xyz personally") so... +1 for googling your therapist or asking for self-disclosure when its important to the reason why you're in therapy I guess lol
