Good for you. Alchohol is a really unhealthy toxin, and I promise you that you are not alone in your dislike of parties. I prefer to hang out with friends and play boardgames or TTRPGs myself.
If you keep your eyes and ears open, you will find like-minded people to hang out with.
I found my current group of friends on meetup.com. You have to actively search, because your people are not at those parties, or bars, or other typical social situations. But book clubs, libraries, hobby clubs, even if you aren’t super interested in the topic, just go join whatever you can find and try it out.
The people you are looking for are out there, they are just harder to find.
