"Consider" asked me on the verdict thread to link to the post about narcissistic injury/suicide. Hope this link works. I highly recommend this book. I bought it a decade ago when trying to figure out my escape from my ex husbands narcissistic family.

"Narcissists very rarely commit suicide. They react with suicidal ideation and reactive psychoses to severe stress but to commit suicide runs against the grain of narcissism. This is more of a Borderline (BPD) behavior. The differential diagnosis of NPD from BPD rests on the absence of attempted suicide and self-mutilation in NPD.
In response to a life crisis (divorce, public disgrace, imprisonment, accident, bankruptcy, terminal or disfiguring illness) the narcissist is likely to adopt either of two reactions:
1. The narcissist finally refers himself to therapy, realising that something is dangerously wrong with him. Statistics show that talk therapies are rather ineffective with narcissism. Soon enough, the therapist is bored, fed up or actively repelled by the grandiose fantasies and open contempt of the narcissist. The therapeutic alliance crumbles and the narcissist emerges "triumphant" having sucked the therapist's energy dry.
2. The narcissist frantically gropes for alternative Sources of Narcissistic Supply. Narcissists are very creative. If all else fails, they exhibitionistically make use of their own misery. Or they lie, create a fantasy, confabulate, harp on other people's emotions, fake a medical condition, pull a stunt, fall in ideal love, make a provocative move or commit a crime
The narcissist is bound to come up with a surprising angle to extract his narcissistic supply from a begrudging and mean world."
