Such sad news about your mom, sending my best condolences.
I lost my mom when I was still a teenager and didn't understand how she got so sick so quickly until my dad told me that her doctor recommended a hysterectomy and she refused to do it. She believed in natural healing and tried to cure herself with herbs and things like that...she never told me or my sister that she had a medical issue. I guess I still carry some anger about that, but my sister was the one who was hurt the most...dealing with life was always a struggle for her and our mom was her #1 booster. My sister never tried to do much with herself after mom died and she ended up passing away even younger than our mom because she ignored her diabetes and heart issues...wonder where she learned that from?
It is a touchy issue when a person chooses to refuse medical treatment...in the end, their wishes must be respected, even if others can't totally understand them.
