I (20NB) have trouble talking to people

I'm not sure if this is the right sub for this kind of post, so please be kind and actually give advice. That said, I have OCD, almost 0 social skills, not a lot of money, and barely go out for a multitude of reasons. I am 20 and every year gets more lonely, and I worry everyday about my Mom and Sister. I can't have them die on me right now, they are the only family I have. I also badly want a boyfriend but I don't really trust guys if you know you know. I just want to know how I can make friends and get used to social rejection and how to get out there in my small ass town. Everyone my age is just online all day or already has a bunch of family and friends they have had since birth but I don't have that. I also don't work because I am legally disabled so no work friends I guess. I also have been trying online friends for years but everyone is horrible and I have had no luck with it. I really need advice on this.
