Believe me please

I'm not crazy.
But why do I even try?
When nobody believes me,
And everybody thinks it's a lie…

I'm not crazy.
Can't you see?
It's just who I am,
This is me…

I'm not crazy.
Don't you get it?
I'm perfectly fine,
But you just don't give a shit…

I'm not crazy.
Should I just give up?
You obviously don't care,
Or even give a fuck...  

I'm not crazy.
But I'm done with trying.
So just leave me alone,
While I lay here dying...
