Narcissists don’t commit suicide. They kill other people.
That said, some pathological narcissists do commit suicide when their adoring/narcissistic supply evaporates.
Take a look at Obama's phone call to his OFA crowd last night...he was very depressed.
The supply is everything to a PN. When it disappears...anything is possible.
Ding,Ding,Ding we have a wiiiina! They think they are the greatest this and when they find out their not, they want to make those that turned their back on Him pay. Like Hitler did at the end of World War 2. Gotterdamerung!
