Narcissistic Personality Disorder (NPD) is a mental health condition in which people have an unreasonably high sense of their own importance. They need and seek too much attention and want people to admire them. They may lack the ability to understand or care about the feelings of others. But behind this mask of extreme confidence, they are not sure of their self-worth and are easily upset by the slightest criticism. 

Narcissistic personality disorder causes problems in many areas of life, such as relationships, work, school, or financial matters. They may be generally unhappy and disappointed when they’re not given the special favors of admiration that they believe they deserve. They may find their relationships troubled and unfulfilling, and other people may not enjoy being around them.

Symptoms of NPD include:

• Have an unreasonably high sense of self-importance and require constant, excessive admiration.
