How to control my anger?

I'm a thirteen year old girl and I get angry so easily. People are always joking about selfharm and call me and my friends 'emos' or whatever because of the music we listen to. I get angry about this and I get envious easily too. I don't know whyy, but my friends are always getting attention from boys. Don't say 'you're only thirteen, you should be happy with stickers' because its not like that. No self respecting young woman would still be joyful with stickers. Anyway, its not like I want attention too, its that I just don't want them to get it. I know this is mean, but everyone I ask doesn't seem to agree with the attention they get either. This also gets me angry and I've broken my hand twice already because I get so mad I end up punching things. Any suggestions on what to do? Councelling doesn't work, I've been seeing someone since I was nine.

Hmmm, message me? I think I can help.
Also, F people who call you emo...same thing happens to me, OTHER PEOPLES OPINIONS SHOULD MEAN NOTHING TO YOU.
