I have mentioned to my T that I post on psych internet forum, but never specifically which one. I've also copy pasted one or two things that I wrote here into my journal, so I suppose she could Google some of the phrases and find out which account is mine. But I don't think that she would. She never really asks me any questions about the forum, I just tell her what ever I want about my posting here, and that's it. So I don't think she's very interested in it. I also don't think that it would be a good idea for a T to try and find someone's account on here, not just because it would be a major boundary violation of the client, but because T's have a lot of clients, and I imagine that keeping everyone straight is already a bit of a job, so you wouldn't want to read something on here, and then get confused, and think the person said it in session.
