Narcissism is a mental health disorder where the person believes themselves to be far superior and more entitled than everybody else on the planet. The person lives in a fantasy reality, which goes beyond mere desire but is the only reality they are psychologically able to accept.

Having a narcissistic sibling is no easy feat as a child or even moving through life as an adult. Narcissist siblings are extremely selfish and manipulative, expecting that they should be able to move all of the chess pieces around the board while you simply fall into line with their demands.

If you’re questioning whether or not your sibling is a narcissist, whether it be a brother or sister, take the Sibling Narcissist Quiz to find out.

  1. This is 100% my youngest sister. Yes, we lived in a very unhealthy, abusive household. Our father was always right he thought. My brother also has emotional issues. I was sexually abused, and our mother was physically abused as my younger sister was. I have had therapy and happily married while my younger siblings have been married/divorced several times.
