I too have had violent fantasies regarding my own death. It was such a relief when I read these fantasies were a direct result of my PTSD. "Sicko" no longer, just a normal person with PTSD.

The books "Wherever You Go, There You Are" and "Full Catastrophe Living" were helpful to me in learning to live in "mindfulness of the moment". Living in moment helped me stop the fantasies when they started. Bascially they have same ideas as "Power of Now" which I have also read.

The fantasies sometimes still start, but I am able to stop them before I am in never never land.

Cheers to all,
