There may be things worth taking your life over, there are a million more to stay alive. The fact that there are people you care about proves that. And if you let the haters get to you, they win. The best way to beat them is to not give a fuck.
Life has its ups and downs, and whilst it may suck at the moment, you have no idea what's coming for you. Don't you dare take your life - sooner or later you'll be glad you didn't.
And there are people who are there for you. Even if it is only the people on this site, someone will be sad if you die. I bet there are more people in real life though.
