Hi Sweetlove,

I've had three different T's request that I bring someone else to a session. I think it's good and helpful for the T to see first-hand interactions between you and the people in your life.

My H has come into session with me several times and it has always been helpful and led to a deeper understanding for everyone.

My mom came into therapy with me once when I was in treatment. That was kind of intense. My T was very harsh with my mom and I was like
It was really scary to hear my mom be talked to that way, and I felt kind of guilty for it. Overall it was really uncomfortable and I don't think I would do it again.

If this is something you think would be helpful then you should do it! You're lucky to have a friend who cares so much about you. I think it is a good idea to talk about expectations before the session, and to talk about or think about what you'd like to get out of it.

Another thing I wanted to say about it is that my T's were all really careful that they didn't disclose anything that I wanted to keep confidential. When my H came into session with me and my current T, there were a couple of times she looked over at me with a questioning look to make sure I was ok with her saying what she was about to say. She was obviously on the lookout for any signs of distress or objection from me and that felt good.

oops....didn't mean for this response to be so long.
Anyway, I hope it ends up being a positive experience for you.
Let us know how it goes, if you decide to do it!
