I feel worthless. I really need some help?

All the guys at school call me gly, I've never done anything to them, and the thing is I know I'm not ugly, everytime I get the chance to leave my small neighboorhood, people always comment on how pretty I am. I dont have many friends, I have about 5 close ones. Everybody makes fun of me though I dont do anything to them. Im a little different, thoguh. I listen to different music, wear differentt clothes, etc. I have nobody to love, no close guy friends, which also kills me. My family life sucks as well, my sister is bulimic and has body demorphic disorder, and my cousin (more like big brother) who lived with me just died from an overdose. People dont know this, they wont listen even though many of my friends know I'm dying inside. I know this is dumb, I just need somebody to reasure me It will be okay..Thanks so much.
