My Mom will die soon, purely due to vanity.
In a NH, 88, parkinsons, dementia and numerous strokes. She wanted her dentures relined so I booked a para transit bus (can't lift her into my truck) and took her to get that done ($500). She has complained ever since that the lower ones make her mouth sore but she's had dentures for 60 years and her jaw bones have wasted away such that there's not much support for them.
I've bought her some healing cream and told her to leave the lowers out so her mouth can heal. Nope, she won't as "it makes me look old, whatever will people think?" ... you're 88, you are freakin old and who gives a d*mn what anyone thinks! I was there today to fix her wheelchair. She's convinced if she could just go "somewhere else" all would be fine. Not happening! Unless she leaves the bottom ones out to allow her mouth to heal, it will never heal.
So now she's refusing to eat ..."I can't because it hurts". ... poor little me, lets do crying, whining and manipulation (that ain't working!) Okey dokey, starve yourself to death in the name of vanity, your choice. She's been a narcissist life long, always on a diet, shopping for fancy clothes, planning her next exotic vacation, trampling on anyone who dared cross her path unless there was something in it for her and refusing to lift a finger to help her elderly parents around the corner, always obsessed with her looks and that obsession will kill her.
No matter what you do, you can't protect someone from themselves, Sad but I've suffered her torment life long and what will be will be. I really don't care.
