Do you act 'emo' for attention? Yes, you do. Cause most aren't struggling and most actually over exaggerate things. Look at the people who actually have it bad, such as hmmm.. those who have nothing to eat, or abusive parents. Do you ever see them, doing things like you do, talking about commiting suicide and hurting themselves in dark ways? No, you do not. You know why? It's all because of their strength and they overcome obstacles.
So please, for those ungrateful people, think, just because someone broke your heart, or your parents don't let you do something, there's no reason to hurt yourself or talk stupid. Seriously, GROW and move on. People have it way WORSE than you :)
