I had problems throughout school where I thought I had a bunch of friends but I was just really bad at telling friends from acquaintances and I actually didn't really have friends.

I'm really worried that I'm in that position again. A lot of people only message me when they want something from me, and I don't get invited to do things with anyone. And people who do things and invite people I thought were friends but not me don't respond when *I* try to set something up and invite them.
