This is a great contest and I hope you enjoy this dark story!!
I killed him because he controlled me in every aspect of my life from when I ate to where I walked, even the time at which I fell asleep, that is for the nights he let me. He needed to die so that I could live, but the problem was to kill my mind, I needed die, which in the end is what he wanted all along.
Thank you for you the psychologically disturbing entry, The mind can be a truly harmful predator to its own vessel!
