I have a therapy session tomorrow and I'd really appreciate your help

Essentially, I want to become more social and make more friends. I only have 1 friend in real life, and currently, we only text each other. We don't meet up anymore.

I want to make more friends, but I don't think my therapist knows that I only have 1 friend. When my therapist asked me before if I had friends, I said "yeah" without actually thinking about what I was saying. So, I think he assumes I have friends and that I'm satisfied with my social life, since I've never actually complained about it.

How do I bring this issue up? It's a very difficult issue for me to talk about. I don't feel comfortable saying that I basically have no friends... but at the same time, I would like his advice and support.

Ideally, I would love for him to help introduce me to people (because he's roughly my age), but I know that would never ever happen because of client-therapist boundaries. That's just a fantasy of mine. *sigh*
