Parts of me

I need to breathe,
But you were once my lung.
I need to sing,
But you were once my song.
And the tears they fall for you
The things we'll never do.
The face I will not see again,
The long way back to heaven.
I need to move,
But you were once my spine.
I need to think,
But you were once my mind.
Alone each time it seems.
Living in bad dreams
When you go you take the heart,
You take the parts of me.
I cannot reach without my hand,
I haven't got nerves to command.
I cannot move without my soul,
Had no choice, had to let it go.
