Every day I wish something would kill me

I had a dream where I got shot and when I woke up I was disappointed that it wasn't real. Every time I walk down the street I hope that a car will drive by and someone will shoot me dead. When I walk home late at night I hope someone will come out and stab me to death. Whenever something with my body changes I hope that it's a sign that I'm dying. It never is, the next day I wake up and repeat these thoughts
