I am the enemy
I can't get out
Of my own way
I am after blood
And sweat and tears
My metallic red blood
And my sad tears
I constantly hurt myself
Every chance I get
If now is it
I speak the truth
Two more short lines
With four more words
Words only for you:
I'm winning the battle
The battle with myself.

And one more thing
Although you physically cannot,
You can trust me
