Ruby,
You certainly could use some help. My father developed Alzheimer�s a few years before he died, and my mother had health problems of her own. Their family doctor intervened and got them help -- meals on wheels, home health care (nurses, p/t, and aids), transportation, and he also recommended my father enter a nursing home a few times when it got too hard to care for him at home. In PA, there is a Bureau of Aging that provides help, perhaps there is a similar organization in your state? Perhaps a family member could make some phone calls for you. You need to focus on your health right now. I wish you the best!
