Thudding

Sitting looking at the wall,
My mind is a blank,
To tired to think,
To tired to care,
To tired to do anything,
Please make this headache go away,
Three days it been now,
This constant thud in my head,
I need to sleep but its thud thud thud,
I close my eyes trying to drift off,
Thud thud thud,
Rubbing my temples doesn't help,
Painkillers don't work,
One thing I I haven't tried,
A dark room finally relief and sleep.
