I think I might have anger issues!?

I think I may have anger issues...in school I am very quiet. I rarely talk in school...long story short...I just never liked talking in school, I feel like I don't belong...the school pretty much has cliques, and no I am not in high school yet. People talk about me behind my back and these four kids made a "song" in music about some kid picking a fight with me and I keep losing to the kid...they don't know me and just typing this reallllllly makes me get MAD at them. I would use a stronger word but I dont know if I really should on here. Anyway, when I go to school I can't look at the other kids that I really hate cause I am afraid I might go ballistic on them. My family comes from a big line of fighters and I know I can fight and the kids at school don't and I am a good kid in school...I am smart and I dont want these issues to get in my way of my good grades. Also, I listen to songs that are by MCR, Three Days Grace, and other kind of bands, I have noticed that most of the songs I listen to have to do with hating someone, two of my favorites are by Three Days Grace the songs are Animal I Have Become and I hate everything about you. So if you can understand what I said and help me with my problem....which is if I have anger issues and if I do what I should do...keep in mind I hate talking to people too...so I really hope you people can help me!
