I'm nothing special

I'm sick of this 
I'm worn out
I am a page that has been torn out
A picture that has been burned
I am sick, I am crazy
I'm always being called lazy
I do my best and I'm told that I can do better
I pray for sunshine, but I can't mess with the weather
I'm the gum off of someone's shoe
I am looking for my reason to live, I truly don't know what to do
I have been told by others that I am crap
Hearing people talk about me behind my back
I am fat, lonely, I can't run a lap
I cover my head, while people tell me i'm a load of crap
I know that most of this stuff is true
But tell me, what am I to you?
