Best of Both worlds

Please set me free
I cant take this misery
The words you said
They keep ringing in my head
My heart is gone
My soul is black
I feel cold and mean
I don’t care what they think
I don’t cry anymore
I have another way to take my pain away
A razor in one hand, an eraser in the other
Can you guess what I’m about to do?
I start to work
This is my best of both worlds
