Narcissism has many faces. In fact, narcissism is not just a personality disorder but it’s also a spectrum. So, what is it? Narcissism is a personality disorder that affects the individual’s self-esteem as well as interpersonal relationships. In short, narcissists are individuals that love themselves more than they love others. In fact, they’re often considered to be egotistical and self-centered. They lack the empathy that enables them to understand the feelings of others. These individuals usually display grandiose behavior and have a very inflated sense of themselves. Narcissism often occurs with other mental health disorders like depression and anxiety.
