Building my Grave

I just want to get out of this jail
I built it bar by bar
I didn't think it would be so big
With bars stretched quite so far
You are not inside with me
You were too far away
And now I wither slowly
And wish that you could stay
I tell you that I love you
But I don't tell you I'm gone
My bones are all that's left
They'll disappear 'fore long
My skin is pale and gaunt
My lips are peeling off
My eyes have sunken inward
My lungs have got a cough
I try to act real happy
To disguise the part of me
That's dying more each sunset
But my soul won't be set free
Its my soul locked in by metal
My heart stuck in iron walls
My body's free to wander
My brain is free for all
But without my heart I wither
Without my soul I cry
I slowly fall to nothing
I think I'd rather die
I finally look around me
And see the jail I made
And that is when I realize
I'm sitting in my grave
