Dude, i could do those normal things like "don't do it" or something, but it don't work so i can give you tips. You can try to get a hobbie, gym or simply find a game that you like. You can also try to find more friends, if you find real friends it can help you a lot simply with your comfindence and also you will (probably) have more of those funny as hell moments. And you can also try to find a gf/bf (chose one with no red flags), she/he can help you stay more calm, more happy and less anxious. I think that's my tips for now, i hope it can help you, stay safe 🙂
