So this is a speculation/correction of a second opinion. Cage's character does not suffer from narcissism he suffers from borderline personality disorder. Here are some of the most common signs, according to the National institute of health. -Constant efforts to avoid real or imagined abandonment: -A lifetime pattern of intense and unstable relationships, often swinging between extreme closeness to intense hatred -Impulsive behaviors such as extreme spending, unsafe sex, substance abuse, and binge eating -Recurring suicidal behaviors or self-harming behaviors -Trouble controlling anger, characterized by extreme periods of rage, depression, or anxiety that may last between a few hours to an entire day - Severe dissociative symptoms, such as feeling cut off from oneself, observing oneself from outside the body, or losing touch with reality I actually suffer from BPD and have experienced a level of psychosis similar to his character. Mine was triggered by severe alcoholism as I imagine was his, or mescaline use. Thankfully I'm sober now and in treatment for my mental health issues. Hdtgm actually got me through some of the dark times so thanks for all the laughs.
