Who will win?

You think you know me, 
but you do not. 
You see the outside, 
which isn't a lot. 
I put up a smile, 
you don't see through. 
Don't blame yourself, 
what are you to do? 
Locked deep inside, 
my demons taunt and torment. 
Bleed out my soul, 
through hell's assent. 
Don't pay heed, 
it isn't your fault. 
Pain is mine to feel, 
through emotional assault. 
Slowly, surely, breaking inside, 
my body breathes but my soul has died.
