My sweet baby has left me

What in the world is left,
Dear Lord, I'm in a daze;
When she has left me,
I'm ravenous, I'm in a craze.

Not sure where I went wrong,
But I can sure take the blame;
I'm not a perfect guy,
I've played my share of games.

I'm revolving without a purpose,
Man, I sure have a need;
My sweet baby has left me,
Left me, because of my greed.
