I don’t think OP is actually interested in making their life better, but for anyone else who saw the post and was like “oh that’s me” there are good answers in the other replies.

Nothing I’m going to write is especially original.

First off, you probably need to be somewhere where there are people. Cities are great. Nowhere, Nebraska is going to make things harder. If you’re out in the country you’re probably going to need to move or commute. There may still be local stuff happening, but with fewer people there’s probably less of it.

But once you find where people hang out, you can probably find a meetup or similar, and go.

There was a board game meetup I went to before the pandemic that had regulars and new people every month. Good way of making friends. I don’t like board games that much, but it was still fun.

There’s a bar near me that runs events from mixers to movie nights to kink stuff. I’ve gone to the mixers and made a handful of friends and acquaintances.

The local library by me does stuff. Lessons, talks, I think they might have book discussion groups.

Stop making excuses. Sitting there going “I don’t like bars. I don’t like board games. The library is too far away. The city is too loud” isn’t helping. You can make excuses for anything to justify not changing, but then you won’t change! You’ll stay just as you are, with opportunities slipping away. No manic pixie dream girl is coming for you. The would-be friend you could make is at the movie night chatting with someone who actually showed up, even though he doesn’t like the genre that much.

If some of the problems are actual blockers, like “I live deep in the suburbs with no public transit and no car”, then cool: that’s your first problem to solve. You’re not really going to get anywhere (no pun intended) without addressing that.
