>>103216I grew up in a very similar "culture" and honestly it sounds like you're doing 100x better than I ever did, considering my first move was to latch onto the first decent man I met and try to get married/pregnant.
The first thing you need to know is you're going to come off as awkward and weird for a long time, even as you really work on your social skills. This REALLY limits your social circles, but it makes your options pretty straightforward. I immediately found kindred spirits when I briefly got into manga and comics because they were so new, but I found good friends after evolving into nerd shit like board games and tabletop RPGs. Everyone around me was at least a little awkward and weird, and seeing how utterly innocent and naive I was, a group of people adopted me out of pity and became very close friends.
As for aimlessness, I felt this for a long time until I found a hobbycraft board, when a nice lady in her 70's at the library explained how the internet worked. I'd worked a small farm all my life, so I had a lot of little bits of crafts skills. Eventually that hobby led me to making terrain for minis gamers, which forced me to learn to paint, which in turn improved my overall skills, which got me a job restoring antiques, then getting a job that paid me to get my arts degree, finally started my career. In my experience, it all snowballs from something you find yourself pre-programmed to enjoy, so don't stress it.
