The concept of nonexistence is very difficult for the human mind to grasp. But I think it's not so much the nonexistence part, but the transition from our animated, thinking selves to the state of nonexistence that causes us so much trouble. I'm not afraid of not existing, because I won't exist. I will have no awareness. There will be no I. But the thought of leaving my life, my experience, and all the people I love is terrifying. It's that terrible process that keeps me awake at night.
