My sister is divorced, kids in 30s aren't able/willing to help. Good logistics yet and remembers people but can't manage $, housework, organizing, cooking, even coffee pot. Uses cream rinse instead of shampoo, extreme hoarding and is very insulted if any deficiencies are addressed. She has dementia diagnosis and homecare coming in to give pills every a.m. but I think she needs so much more.
You could try a call to Adult Protective Services to do a check on her. The person help with her meds may have a similar opinion. Have you chatted with the med manager?
