Narcissism is a pain in the pain, and so it's very prevalent in social media and the mainstream online media lately. My last girlfriend was a terrilbly nasty gaslighter and an NPD-traiter. (Narcissistic Personality Disorder.) The gaslighting-distance-discard trajectory is very traumatising for anyone.
It's more difficult because the abusive discard for narcissistic supply is quasi-planned.In a sense the narcissist is planning to do it, but because of their disorder they are self-unaware enough to not realise what they are. Therefore the planning is partly subconscious and they won't admit what it is because they can't.
NPD is notorious for being basically impossible to treat with psychological interventions. Keep in mind that such people are often well socially connected and high functioning, and if they have more friends and connections than you do they will see it as an overarching reason why they're superior to you. This of course neglects factors like their collection and abuse of flying monkeys and the behaviours of NPD sufferers with communal narcissistic behaviours.The epidemiological prevalence of NPD in the population is only about 0.5% to 6.2% in the general population and most 75% of NPD are male. Rates are typically higher for men (e.g., 7.7%) compared to women (e.g., 4.8%).
The DSM-5 reports that up to 75% of those diagnosed with NPD are males.
It's important to note that while men may exhibit more "grandiose" or overt narcissistic traits, women may express narcissism differently, often leaning towards "vulnerable" or covert narcissism, which can sometimes be misdiagnosed as other disorders like Borderline Personality Disorder (BPD). These are often comorbidities.
Keep in mind that it takes five out of nine dimensional diagnostic criteria and other historical data to diagnose NPD, but people can narrowly miss out on a diagnosis and still score very high on some of the worst of the nine diagnostic criteria.
