A narcissistic breakdown — also called narcissistic collapse — occurs when the external structures a narcissist depends on to maintain their self-image fail simultaneously or catastrophically, leaving them unable to regulate their sense of self through the usual mechanisms of control, supply, and impression management.

Narcissistic rage is an intense, often disproportionate emotional reaction — ranging from cold contempt and silent punishment to explosive anger — triggered by a perceived threat to the narcissist's self-image, control, or sense of superiority.
