Help with school home ect..?

My best friend started telling everyone I'm emo becausei was having problems at home and my life is misrable. I hate most of my family (excluding my mom and brothers) but anyway I have friends who are emo and cut themselves. Im tired everyone at school nearly avoids me cause I'm ckinda annoying. My brother who's a football jock whos great at sports calls me gay cause I hang out with alot of girls and hate sports. My mom won't tell me this but I know she thinks I'm bi cause she hinted at it and I'm so sick of it. I'm cooped up at home because my brother constanly is getting invited to parties and stuff and I'm not and at school no one will talk to me at all pretty much beside just a few friends that I've managed to convince but are still kinda mean to me, Also I'm tired of being called emo when i'm not.. even tough I know I could be if I wanted I don't want to and have never cut myself but have tought about it because of my friends that are emo. Can someone help me please...
