how do yall cope with being lonely, and how do i fix it

So basically, I (20M +ASD) have never really had any irl friends my whole life, even now that I am at university. When I was a child my friends online came entirely from the mlp board on 4chan(😭) and minecraft servers, which i feel is a terrible combo because now i am 20 years old and dont really have any social skills at all. I have a few online friends now, but they all have girlfriends and active irl social lives. To them, I'm just the guy they play games online with sometimes, but to me, they're the only social interaction I get. It's reached a point where I have a hard time leaving my dorm room because im reminded just how lonely I am, and every time I have a social interaction it is just painfully awkward, because this is my first time being in a city and not isolated with my family in a tiny village of 80, I've also done some things that I had no idea made me seem really creepy until months after, and people even look at me like a creep when I go out. For context, I go to a major greek life school, where there isn't much to do outside of bars and frats, and I've tried going to clubs including the neurodivergent club but all the meetings got cancelled because I was the/one of the only people to show up. I hate having autism how do i fix this :((
