Dont want to go to camp?

i go to sleepaway camp for 8 weeks over the summer. this will be my 5th year. im turning 13 and i want to be home for my birthday. i've been trying to convince my parents not to make me go EVERY year before camp. my sister goes and she loves it (i think) i really want to stay home this summer and i get really upset every year before i go. both my parents work, but my dad ends on july 6th and goes back august 14th. he goes to the beach everyday and they go out almost every night and they do fun stuff (go into the city, go out to eat etc.) and i really want to do that with them. i just got into a really bad fight with one of the girls in my bunk and i dont wanna go to camp!! what can i do?
