I think it's likely that Kim has Narcissistic Personality Disorder - horrible childhood has resulted in her donning this ridiculous lovely granny facade, as seen when she's with Jedward, but the twisted, manipulative, nasty, demeaning , unhappy Kim comes screaming out as soon as she receives any criticism or is disagreed with.
She has an extremely fragile ego and a HUGE persecution complex; always playing the victim ("you've put me through hell", "you started it" "tell them off not me"etc etc)
Tbh I feel sorry for her as she arguably (I doubt having a personality disorder classes as a mental health problem but when someone becomes pathological I think it's fair to say it does) isn't mentally fit to be in there.
OR she has early onset dementia and therefore definitely shouldn't be in there.
