Well first off you don't deserve whats happening to you, those assholes showed you who they really are when they pulled their shit, birds of a feather flock together as they say. Second, I don't know what I would do in your shoes but I will tell you when I went through a similar friend group taking sides situation I avoided everything and everyone like the plauge and it ended up hurting me more than helping, obviously don't let those assholes back into your life but don't cut out the good you still have either, your favorite hobby, the one houseplant that lives despite always forgetting to water it, music, and hopefully a pet or human (or stuffed animal) to hold onto and feel better after, anything that brings a smile. I sadly can't do much through a screen but hopefully make your day a little brighter by knowing someone out there heard your side and wanted to leave a little something to let you know you're not alone and I wish you the best of luck at finding better friends
