I had a T who had recovered from the same thing I was struggling with (anorexia) and she never told me (my mother ended up asking her and found out that was, I never approached the T about it). I think it really, really would have helped me to know that she was a fully recovered person. I went so long feeling hopeless that recovery was even possible, knowing an example (who I could talk to for an hour once a week) would have been quite motivating.
