Tears on a Pillow

This came to me when I was trying to sleep one night. I never really got poetry.

I lie awake while my head rests
My mind constantly racing
As I lay on my breasts

Can't help but think about my past, present and future
Wishing that things were different
But my brain picks at itself and it's torture

Next I know I am drowning in sorrow
And suffering in agony
Shall I wake up tomorrow

I soon realize I am at an all time low
And it runs like a river as long as the Nile
With all these tears on a pillow
