I am not the doctor, but I have been dealing with a "True"
narcissist for a long 10yrs. My ex wife is a "True" narcissist. My ex wife has
physical custody of my children. Before my ex wife and I divorced, we both took the
MMPI testing during the course of our marriage and family counseling. We both subpheona each other's test results during the course of the divorce. My ex wife was attempting to prove via the test that I was clinically depressed and thus an unfit spouse and father. I found out via ex wife's test results that ex wife had a very bad personality disorder, Narcissisium. And her narcissism had fully developed.
There is a web site and author of a book that explains narcissism. The only advice I can give you for dealing with a "True" narcissist, is that if you can stay away from the person that is a narcissist, the better off your life will be. A "True" narcissist is a very sick person and will make any person's that has a direct realationship with the narcissist, crazy.
A narcissist has to have the approval and praise of person's that are close to them. This approval and praise is like the need of a drug for a drug addicted person. Also a narcissist is a very self centered person, and it's whole view of the world is about the narcissist/person. A narcissist views person's that are close to them and others, are only to be used by the narcissist. And a narcissist will use person's to only benefit the narcissist and other person's that the narcissist comes close to are viewed "only" as what they can do for the narcissist and serve no other purpose.
The narcissist I have been dealing with only views it's children as a possesion. The children have no other use or value other than to validate the narcissist's need to prove to others that this narcissist's is a good mother. That this narcissist will go to great lengths to prove to other's a myth that this narcissist is a good parent/mother. But behind the secenes and behind closed doors this narcissist is a horrible mother and has done horrible things to my children(neglect, verbal abuse, spend all monies for the narcissist's benefit not the children's benefit, ect.)
Also, a narcissist will lie, steal, fraud, and do just about anything it wishes. A narcissist does not have conscious. Also, a narcissist spends it's whole time attempting to portray something it is not. A narcissist is in a constant search and constant attempt to portray it's self something other than what actually the narcissist is. Also, a narcissist will lie, steal, cheat, or do just about anything to win. And I mean win at anything, win arguements, win court battles, win at any sports, win at any games, win the approval of others, win the praise of others, ect. ect.!
Also, a narcissist's does not like to be considered common or as a common person. A narcissist's always thinks it's self as
being/having "grandeur".
