For awhile in late 2012 I thought I had already killed myself, I was already dead, everything I was experiencing was just a hallucination in some kind of bizarre afterlife.  Part of the reason I believed this is people were acting just the way I would predict them to act so I stopped thinking of them as people and started thinking them of projections.  I believe that call this Cotard’s Syndrome and it’s a certifiable mental illness.  The interesting thing is the treatment is just doubling down on the anti psychotics I’m already on.  These anti psychotics basically shut down the lucid part of yourself (especially in higher doses).  So treatment for someone who believes they are dead is killing the off-the-rails lucidity that helped create this idea.  In a way zombifying them, but making them dead in a way that is acceptable to society.
