I really gained a lot from reading that
https://www.psychologytoday.com/blo...nship-between-narcissism-and-bipolar-disorder.
In particular an explanation of how one can become narcissistic.
"
The developmental origins of a specific personality organization are not algorithmic. It's not like all people with strong narcissistic traits have been subjected to the same developmental influences. However, there is enough consistency in its pathogenesis to say it does frequently entail an individual's early needs to be developmentally more advanced than one's age, a sense of insufficiency, lack of adequate attunement from primary parental figures and an experience of the developing self that’s diffuse and not well-formed. And yet despite the experience of deficit, the narcissistically organized individual has learned to draw on specific strengths and capacities in order to distance from felt vulnerabilities or weaknesses. If you think about it, it’s actually a remarkable early developmental adaptation."
and this is how the personality syndrome comes into play and manifests itself...
"Narcissistic individuals have developed the capacity to inflate, expand upon and intensify their strengths. They learn to lead with them in such manner that their experience of feeling small or vulnerable is masked by the presentation of just the opposite"
and then this
"narcissist is strongly invested in his or her strengths because they are employed in the service of protecting or buttressing the self against the experience of insufficiency. Temporarily, all are fooled by this compensatory counterbalance, including the individual behind the narcissistic mask.
and so I can see how intense oppression by the Cult can break a person ( narcissistic injury ), or drive them into a malignant narcissistic mode especially if that oppressed person has "stored patterned organizations or one might say "identity patterns' or perhaps somewhat akin to schizophrenia and similar to what is discussed in Identics.
And we get an uncontrolled (by the individual) shift of mental framework and a somewhat corresponding bewildering activity.
"But the dilemma is that the narcissist must intensely invest in the defense because any crack in the armor can lead to a precipitous collapse into realms of the self that are intolerable. The personality structure lacks adequate flexibility and the individual is prone to feel rapid onset of acute pain when his or her narcissistic style doesn't work well enough to acquire the love, admiration, power or control the individual was seeking. This pain, brought about by the rapid collapse of defenses, is what we refer to as narcissistic injury."
combined with
"Conversely, the narcissist's grandiose self-perception is more enduring. The experience of superiority is called into play with enough frequency that it's an integral aspect of the individual's self-perception."
There is much more in that article "The Relationship Between Narcissism and Bipolar Disorder" by
Russ Federman, Ph.D., ABPP is in private practice in Charlottesville, VA (
www.RussFederman.com).
Anywhoo that is one look in on it. There are plenty more views around and about "Dissociative identity disorder (DID), also known as multiple personality disorder (MPD),[1] is a mental disorder characterized by at least two distinct and relatively enduring identities or dissociated personality states."
