How do you actually make friends and meet new people?

Honestly, I've been becoming more and more lonelier through the years. I stopped hanging out with most of my past friends for stupid reasons, like for their comments about ugly people or their boring (according to me) hobbies, to name some. I don't know if I should've done that, as my current friends don't hang out much, so I can perfectly have a full month without much social interaction, besides my parents.

I honestly have lost the will to do most things: I don't feel like hanging out, even on the rare occassions my friends want, I stopped going to the gym, sometimes I forget to shower/brush my teeth, I just don't really enjoy listening to music or playing videogames, like I did before. I just want new friends I could talk to.

But here's the problem: all the friends I've had in my life have been from Highschool/College. I've tried making new friends through accquaintances, but it didn't work out. I'm autistic, so it must've been because of my poor social skills, or something. I guess. I don't really know where I can actually meet people my age. I just don't wanna be so lonely anymore.

I think I should go to therapy, as most of the time I'm just replaying bad memories: the times I got called ugly (last time was in 2024, by two men, at a restaurant. They were sitting on a table, that was facing towards ours, and they were talking about how ugly I was. After having eaten with my friends, I just said I was feeling sick and returned home. I had an anxiety attack there), when I got bullied for my lack of intelligence and autism, when people would describe me as ugly behind my back, etc. In all honesty, I'm kind of a hypocrite in this sense, because I also judge people on their looks, but in an opposite way: if someone is attractive, I just tend to think they're an asshole and try my best not to associate with them.

I'm ranting at this point, so I'll just ask this one question: where can I meet people and make friends?
