I've seen the list of Jack's claimed health issues and I just wanna say I'm all for examining the likelihood of Jack's multiple diagnoses but also there are some genuine people out there with a laundry list of health issues. It seems like that's the latest accessory for internet personality narcissists though.
I just say this bc I have had a history of anxiety/depression/panic attacks/body dysmorphia/eating disorders (usual teenage girl self loathing combo, diagnosed by MH professionals) but also I have a bunch of allergies, scars, medical-related PTSD and a cancer diagnosis under my belt. I'm sure there's other people on this thread who have hospital files big enough to knock someone out with too and I just wanna be clear that we're saying Jack's ongoing list is an aspect of her narcissistic behaviour, and not narc behaviour in and of itself!
