Narcissists don't kill themselves.
Suicide weekend isn't literal.
>Narcissists VERY rarely commit suicide. It runs against the grain. They have suicidal ideation and reactive psychoses under severe stress – but to commit suicide runs against the grain of narcissism. This is more of a BPD trait. A differential diagnosis of NPD (which distinguishes NPD from BPD, for instance) actually almost rests on the absence of attempted suicide and self-mutilation.
