Social anxiety??

Does anyone here have social anxiety? I've had it since I started middle school (I'm a junior in HS rn) and it's really ruining my life. I spend all my weekends alone and I've completely isolated myself from all the people I used to be friends with and its so miserable. I don't talk to any boys at school because I feel like they all hate me. I've even considered transferring schools just for a new start. Does anyone have some tips? 😞
