My DD16 has been 'friends' with a girl since year 3 of junior school. She has always been possessive, jealous, controlling and often down right nasty to DD. I have now been told by one of this girls family members that she has been diagnosed with Narcissistic Personality Disorder. This makes perfect sense as reading up on it she is displaying all of the charactistics of this condition ie lack of empathy for others, feeling of superiority, expectations of special treatment from others, unrealistic self opinion of her own looks and abilities. I just wish DD had the courage to withdraw from her, which she does periodically but always ends up being drawn back in as it's easier to be so called friends with her than enemies. She is very manipulative and will make up rumours and lies about those who won't do what she wants. Any tips on the best way to deal with her as it looks like she's going to still be in our lives for a good couple of years yet!
