How do fuck do you make friends in HS?

schools out in 17 days, I’ll be a senior next year, I’m not that social and this year I was all depressed and shit so I was isolating myself. I’m so lonely it HURTS, I literally feel an ache in my chest when I think about it. The last friends Ive ever made was in sixth grade but then I lost contact with them during the pandemic. I’m pretty much just the quiet kid, I hardly talk, and even when I do I usually mess up, I also feel like I make people uncomfortable purely with just my presence. I’m not ugly and I’d even kind of consider myself a tiny bit above average in looks so I don’t think that’s really a problem, but I don’t know anymore. I always wear a hoodie so I guess that makes me more unapproachable, some people in my class actually know my name but I don’t know if I want to pursue a friend ship with them on fear of losing what little I already have with them. And how would I even approach them to start a friend ship??? That’s my BIGGEST question.

Also, Kind of a pathetic, small last question, if you have friends, do you talk about your mental health with them, or is that weird?

Sorry if this is kind of pitiful I don’t know where else to go.

I’m a guy if it matters.
