How do you make friends?

(F19)

I have absolutely 0 friends. I used to have some, but I lost touch with a lot of them over quarantine. I have been homeschooled my entire life, meaning I didn't socialize that much ( When I was younger, homeschooling wasn't a popular thing, so there wasn't many after school activities to meet people ). I have really bad trust issues, I also feel that if I tried to make friends, I might end up making it toxic, not on purpose of course, it's just my own personal issues. I'm just tired, mentally and emotionally drained at this point to where I don't think I can give/add much to the friendship. The thing is, I haven't had much socializing the past 4-5 years, and I'm starting to get lonely, even though I hate admitting it. I just feel like I need friends, and not online friends, but friends I can physically hang out with. I also have health issues that are considered disabilities. I got officially diagnosed with the conditions when I was 14, which was the beginning of covid. I'm scared people will leave me out of things, or there only going to be my friend out of sympathy.

All this to say, and it sounds stupid, but how do you make friends? I know by joining in activities but the issue is, I'm 19, so I can't go to any school activities, which makes it hard. I'm scared, I'm scared that I'm out of time to make true friendships. I don't want to be alone for the rest of my life.
