I'm not really sure how to do this anymore

I'm a 23 year old male and I live alone, but I feel stuck when it comes to dating nowadays. I don't think I'm at all bad looking, I would say I'm a 6/10 to most people, but things were just a lot different in high school. Now everything is like a game of chess where you have to make all the right moves and say all the right things all the time. I've tried dating apps and that worked out just about how you could imagine, and I figure the only other way to meet poeple is to meet them in person. The problem is you can't really just go out a meet people by yourself that easily in a small-town nowadays. Especially if you're approaching a girl within a group of friends. If you're alone, the 1st thing she's thinking is "why is this strange man all by himself trying to talk to me?" And if she's with her friends, she's almost gonna feel encouraged to turn you down just because of the reaction she'll get from her friends. So I just wonder what the heck I'm supposed to do. I myself don't have any single friends that like to go out places so my options are pretty limited. I'd like to think I'll find someone eventually somehow (maybe just by bumping into each other getting groceries or something) but the longer I try, the shorter the days go by and soon I'll be single and 35
