What Am I fighting for?

I went to your grave yesterday to see how you were doing. I guess every time I go there I'm waiting for you to pop out of the grave and say boo, it was all a joke. But months later and you're still dead. It feels like just yesterday it was grade ten when we first became friends. Sally gave me your letter and the journal you like to call book. I'm so sorry I wasn't there for you when you needed me most. I was hiding in the dark. So I'm passing it on to the world so they know what really happened to you. I still have one question that's always on my mind. Did you really kill yourself or were you murdered?
