What’s my issue?

I’ve been an outcast for what seems to have been my entire life, at least since during elementary school. Of course this has an effect on how I perceive social interactions, but sometimes the “it’s in your head” argument doesn’t really apply to a situation. Case in point: mine.

For the past couple months I’ve been trying hard to make friends at college. I’ve been joining clubs, asking to go to lunch with/talking to people in my classes, going to parties/social events, and trying to make small talk whenever I could. It doesn’t really seem to be working, however as most of the time I get treated with a cold, uncomfortable distance, whether I know the person or not. People ignore me in group conversations most of the time; if someone does respond, it’s usually in a somewhat mocking way. When I’m invited/“included,” it seems to be out of pity rather than an actual desire to hang out with me, which lines up with the fact that most people also talk down to me. Nobody texts me or includes me in group chats (besides the class ones, if that). My roommate doesn’t particularly like me either (but that’s a bit of a story for another time), and even though he’s not particularly outgoing he seems to have people that actively like him.

I honestly am at a loss as to what I’m doing “wrong.” Because honestly, it’s probably not “just me” or “in my head” that people don’t like me. While I’ve asked a couple people I’m actually decently “close” with about if I’m disliked (to which they said I’m not, or that they haven’t heard anything), I still sense that I’m at best a background piece, and at worst actively seen as a nuisance. Maybe I’m just really chopped to be honest.
