What should you do when you just got ditched by all your friends and you're sitting at home, crying?

basically today was supposed to be one of the best nights ever and i literally spent 2 hours getting ready only to find out that ALL of my friends bailed and went without me. (they went earlier then we agreed on and didnt tell me) now im stuck at home and i cant stop crying. i dont really know how to cheer myself up….any help?
