I need help

I'm (23F) not doing okay. Not at all. I'm not motivated with studies because, while everyone is starting their lifes, I'm stuck in college. I'm totally alone, not friends or partner. Nothing. I'm just a waste of space and a burden to my parents. And I don't know what to do. I don't even have a single friend or someone to talk to and it's just so pathetic and disgusting that everytime I think about it I just know it will always be like that and there's nothing I can do about it because I just don't know how to approach people and I'm not approacheable to people either. And I don't know what to do to have just one single friend. Sorry if I'm writting this horribly, but I need to get this out from me because it's really killing me.
