i don’t get along with most people

I just don’t enjoy socializing with most people. A little bit here and there is fun, like catching up with coworkers at the office or old friends, but prolonged interactions w ppl i’m not very close to/comfortable around is not fun for me lol. for ex. a kickback w/ a bunch of ppl where ur just sitting around talking doesn’t sound fun at all. idk. it takes me a while to find ppl i want to be friends w. idk why im so picky. i just don’t feel comfortable around most ppl to be myself and being around them gets exhausting. Usually, i can tell from the get go if i will get along well w someone. anyone else? idk. i’m just extremely introverted ig
