Many years ago i had a best friend dealing with the same issues i did and she wanted to see my therapist. I thought my therapist was wonderful(little did i understand back then she was terrible). So i encouraged my friend to see her.
Bad decision.
It started out fine. But after a while some kind of "subling rivalry" started between us. It was like she started competing with my for our therapists attention and love.
Eventually, things got bad. Lets just say i no longer speak to that girl, and that therapist disappeared out of my life eight years ago.
