Who am I

Beyond the skin, a smile embraces,
Beyond the skin, the laughing faces,
Beyond this skin, the happiness places.
Beyond my words, the darkness lies,
Awaiting such days of my demise.

You see my smile, but it means tears,
The bitter days through out the years.
I thought I new such line was straight,
But I stray afar with every pace.

Inside my voice screams in anguished pain,
Hopes of beauty, are they in vain?
I'm just trying to maintain,
The false sanity so humane.

Can't I fight to sustain?
And prevent the application of propane?
Then throw this match, am I insane?
To spread my corpse along the lane.

I ask of you, can't you just see,
I'm only trying to live, to be me.
But who am I?
