Νάρκισσος (Narcissism) is a psychological concept that refers to excessive self-love and an inflated sense of one's own importance. It is derived from the Greek myth of Narcissus, a young man who fell in love with his own reflection in a pool of water. This condition can manifest in various ways, including a lack of empathy for others and a constant need for admiration. In psychology, Narcissistic Personality Disorder (NPD) is a more severe form of narcissism characterized by grandiosity, a strong sense of entitlement, and a tendency to exploit relationships. Individuals with NPD may struggle with maintaining healthy connections due to their self-centered behavior and difficulty in recognizing the feelings of others.
