Narcissists invariably react with narcissistic rage to narcissistic injury.
Narcissistic injury (or wound) is any threat (real or imagined) to the narcissist’s grandiose and fantastic self-perception (False Self) as perfect, omnipotent, omniscient, and entitled to special treatment and recognition, regardless of his actual accomplishments (or lack thereof).
The narcissist actively solicits Narcissistic Supply – adulation, compliments, admiration, subservience, attention, being feared – from others in order to sustain his fragile and dysfunctional Ego. Thus, he constantly courts possible rejection, criticism, disagreement, and even mockery.
The narcissist is, therefore, dependent on other people. He is aware of the risks associated with such all-pervasive and essential dependence. He resents his weakness and dreads possible disruptions in the flow of his drug: Narcissistic Supply. He is caught between the rock of his habit and the hard place of his frustration. No wonder he is prone to raging, lashing and acting out, and to pathological, all-consuming envy (all expressions of pent-up aggression).
