I for one definitely feel this way. I did have to come to the harsh realization lately that most of my friend group and I didn't actually have the kind of mutuality that most friends do. Meaning I realized they were probably hanging out with me out of convenience, because I always asked them to, and/or they felt sorry for me. Maybe not so much the last one, but I don't think there was a great desire in them to actually be my friend. It was more just proximity. And my T asked me when the last time I can remember having a truly supportive, mutual group of friends was and I couldn't actually remember. Seems it's always been this way, that I kind of latch onto people who will just...let me do so. And then I become resentful that they don't actually treat me like a true, solid friend would.

I don't know if this makes sense at all. I do have a couple of people who I can say are friends, and I think from here on I will be more careful about choosing quality over quantity (even though I didn't really have quantity, either). OP...does any of this seem familiar?
