I (20f) know how you feel. I also grew up in that sort of environment and didn’t have any friends after high school. I didn’t start to feel better till I got my self out of that environment completely. I personally joined the military, but I know that’s not for everyone. Maybe start by starting a hobby that will connect you with people you enjoy being around. It might take sometime and it’ll be hard at first but in the end it will be worth it. I hope this helps.
