83 year old mother

I need help. my parents are in their 80s, my dad thinks he will live forever and my mother is constantly saying stuff like "oh god! why can't I die" as she grabs the coffee thermos to gest throwing it at me. She hasn't bathed in nearly 3 years. Yes, years! we had the bathtub removed, a walk-in shower with bars installed, a bathing/shower chair, i even bought her water proof walkeetalkees so she could communicate. She refuses to bathe. she thinks wiping herself with a WetOne (those damn single use towelettes) is enough. Her feet are so disgusting and crusted in dead skin from never being cleaned. She gets violently mad at me when I tell her its time to stop being gross and to get a life! They keep telling me I am useless and have welfare mentality whilst I work full time as a supervisor, I do not eat their food, and I basically clean up after both of them every single day including flushing the toilet for my dad who thinks he's somehow saving money by NOT flushing.

to make matters worse my dad has a property with a fair bit of land outside of the city that I have been telling him to sell for a good 30+ years, since I was a kid anyway. He refuses. He thinks he is doing me a favor by burdening me with this shit.

They are not long for this world. Its obvious when the night comes and the mood-swings kick in, but they absolutely refuse to admit it or take ny accountability- its easier to blame me!

I have reached out to the Alzheimer's society, here in Winnipeg, but unless you're in a hospital bed they don't want you. the Manitoba medical system is so over-loaded that they want seniors who cant take care of themselves to live at home. They will not accept home care. I am at my wit's end. My mother is so miserable! She quit smoking cold turkey about a month ago because no one would go out to buy her cigarettes. It's a miracle that didn't kill her. The only way to have peace again is to probably buy her a carton (which she will smoke in the house, because, heaven forbid she get some sunlight or fresh air).

I don't even know what I need help with specifically. I just... I am tired of getting called "retarded" by the ones who are mentally ill and unwilling to get help for it!!
