It's alive.

I wish I could explain it,
this constant thrumming.
It's like a pounding -
nay, a humming.
Constantly picking.
Numbing.
It pauses. It moves.
It's alive. Won't die.
Can't die. Can't die.
I check every now
and then.
Are you still breathing?
Are you still beating?
Are you still seething?
Breaking? Scratching? Biting?
It won't go away. I can feel it.
Feel it somewhere in my brain.
Can't kick it out. Can't kill it.
...need it?

Do I need it?
can I live without it?
