What should I do about my eighth grade formal? :/?

My formal eighth grade farewell formal is coming up and I really do not want to go! Ugh I just hate everyone in my grade and don't wana spend anymore time with them and the only reason I'd go is just because everyone is going and I'd be weird if I just didn't go and my parents will make me. I'm also going to have to buy a dress and get dressed up for something i don't even want to go to. What should I do to make it through the night without feeling terribly akward and lonley? ):
