The Circle of Pain

Where is the end
at in a circle?
How can you tell
when you are
at the beginning?
Is the middle
inside the circle
on the outer edge?
Does the circle
begin at the ending?
I was doing so well
but now I am back
in hell.
Maybe it takes hell
to appreciate heaven
or at least the idea of them.
Torture time.
I did not know it was that time.
I guess I forgot to set my watch.
But this seems like my
first time back in the circle.
I freed myself from the boxes
but forgot about the circles.
I wonder how many circles
there are?
And where are the circles at?
Are the circles just more boxes
that have been rounded off
or are they different entirely?
