I think I had a very similar experience while making the high school-college transition. My freshman year started in 2020, middle of covid, and I had no friends at my school. Up until that point I was very introverted, but I forced myself to just talk to anybody I passed by on the off chance I can get a friend or two.
I can tell you it gets so much easier. There's more varied people, and you can find folks that really build you up and just *not* hang out with people who don't. And no one knows or cares about all the embarrassing shit from the past, you get a clean slate. Good luck and enjoy college!
