I'm not jealous of my T's clients or anything. I do worry, sometimes, that she has clients who I know. I see my T at a university clinic, and the clinic doesn't have very many therapists. A lot of my friends are in therapy. I don't know who they see. What if it's my T? What if when I talk about my friends, my T actually knows who I'm talking about?
To her credit, of course, my T has never ever let on that she sees anyone I know. I just know it's a possibility.
