To know thyself

Would that I had never known me!
To have been ignorant, so many years,
And died a blissful death,
Without ever having met me
For there was hardly room enough before me.
And now
     I choke, stifled by the presence of one who will never leave.
He is always here.
And I am always here.
And we duel for control over my body.
     My mind.
          My everything.
               My nothing.
