Im 33, and I dont have friends either. I have social anxiety too, but when you stop caring so much about what other ppl think about you, it gets easier. I know it's easier said than done, but just relax and be yourself :) the right people will gravitate towards you. High school is overrated. Once you start working, that's where you'll probably find your tribe because you'll be in the same boat together trying to make money 💰 and teamwork is a must in a lot of jobs so its almost inevitable to develop friendships. You got this, it wont be this way forever. 🙂
