I know I'm nothing

There are things that used to make me smile
One of them was you for just a little while
You left me for dead so far away
I replaced you with fear and shame
You'll be happy on the day I die

There are things that used to make me laugh
But now they're deeply buried in the past
I left them there so far away
Replaced my humor with my pain
I'll be happy on the day it dies

There are things that used to make you cry
One of them was me for just a little while
Why is it that you had to say
Goodbye in your special way
