Dark and deep and black

I look inside a vacant hole
That's dark and deep and black
It reminds me of the strength that leaves
And all that I may lack.

I'm continually reminded of drawbacks:
It's dark and deep and black;
You may think that the strength leaves
But all that fortifies I stack.

Time may be precious and I have little left
Cause it's dark and deep and black;
I didn't mean to hurt you, I meant the wishes;
Can't you see it's dark and deep and black.
