That would make me super uncomfortable. When therapists overshare it creeps me out. I feel like the client doesn't need to know that much about the therapist. Unless its trival things. And Especially when it is not related to stuff. The therapist I had before I moved told me she suffered from a mental illness for a bit that did not relate to anything I was going through. She also admitted that I had an annoying personailty but I didn't really mind her saying these things to me since I just wanted to please her. With my current therapist I don't really notice any legit red flags except for a few odd comments that I just chalk up to maybe being a bit naieve and inexpirenced.
