What should i do.......?

ok so my life hasnt been so good lately, my grades have been dropping people are starting to be mean to me because of false romours and my friends are starting to not like me because they are starting to think they are to popular to hang out with me and today all of us were going to go see hangover 2 we have been planning to go for a week and it was my idea and now they all said they arent going but i over heard them making the plans when he sent a txt to the wrong person and i was in a xbox live party before one of them kicked me he said.."gotta go the movie is starting soon" so they lied to me and went anyway
