Narcissism could be defined as the ability to maintain a positive self-image. It manifests itself in the form of normal or pathological. Normal narcissism is the foundation of a person's self-esteem, mature dealing with emotions and the ability to achieve quality interpersonal relationships. It underlies the need for social recognition and acceptance as well as the motivation for self-improvement. On the other hand, pathological narcissism is characterized by an inability to maintain healthy self-esteem and consequent dependence on external affirmations of self-worth, an inability to regulate emotions such as shame, envy and anger, and an exploitative approach to interpersonal relationships. Pathological narcissism is divided into grandiose and vulnerable narcissism, depending on the openness or concealment of grandiosity, the prevailing mechanisms of regulation of self-esteem and emotions and the way of behaving in interpersonal relationships. The psychic structure of pathological narcissism is based on the simultaneous presence of a false ideal image of oneself within narcissistic grandiosity, deeply present narcissistic vulnerability marked by feelings of shame, worthlessness and inferiority and narcissistic defenses that represent rigid and comprehensive mechanisms of maintaining that dichotomy.. Narcissistic injury poses a real or perceived threat to the self-esteem of narcissistic individuals. In the case of experiencing narcissistic trauma, a decline in fragile self-esteem results in a heightened sense of shame, worthlessness, and inferiority. These feelings, especially shame, arouse narcissistic anger that can result in aggressive behavior. Anger and consequent aggression can be directed towards threatening objects, but also towards the subject himself. In the case of targeting the subject, aggression can result in suicide. Also, suicide can be a way of revenge on an object.. Suicide represents the conscious causing of one’s own death, while suicidality is a broader term that encompasses the full spectrum of suicidal behavior. Suicidality also includes suicidal fantasies that can serve as one of the foundations of narcissistic persons' feelings of superiority and uniqueness within narcissistic grandiosity. It is also known that different cultures have different influences on the association of pathological narcissism and suicidality. Therapy of suicidal narcissistic patients is based on suicide prevention in states of acute suicidality and psychotherapy of pathological narcissism.
