Have you ever been so sad it burns?

Have you ever been so sad it burns?
At the bottom of your stomach, it twists and turns.
I feel that way a lot these days.
As I stare out my window pane.
I hear the noise outside the room.
But it never knocks to see me too.
Content with who it has to do.
Not needing someone else to tune.
So I sit here all alone.
Waiting for a thing unknown.
To take the horrid pain away.
And maybe even think to stay.
