For a starters, cut the whole emo slitting crap out, no one cares and it's probably attention seeking.
Second of all, you're twelve. Go play outside instead of having girlfriends and saying life sucks.
Thirdly, you're twelve. You've experienced 1% of life. You're probably making this because you've gotten grounded.
And finally.
People have real problems. You don't. What about everyone who is starving to death or are on the streets? Go watch some cartoons or something kid.
Another last note. I listen to Metallica, Parkway Drive and Iron Maiden. Try listening to people who don't have emo fringes and more make-up than a fake tanned girl.
