Anxiety

I have a hole in my chest. No one can see it 

and no one knows,
but it's definitely there.  
And it moves.
Sometimes it's in my throat.  
Or my heart
Or in the front of my chest before my ribs
Or in my back in the middle of my spine 
And it varies in size.
It comes when I sit too still for too long and 

I'm too quiet.
I worry.
