Elder Care Anger and Resentment - Only Child

I have no brothers or sisters to help me care for my elderly mother. My husband will help, but he will only do what I ask him to do. I still have to figure everything out, schedule and arrange things by myself. No one is around to help with any decision making. Not long ago, my own health was perfect, but after menopause it seems like I'm having more and more physical problems of my own.

My mother's older sister passed away last year. Almost immediately her own health started to decline. I think some of her physical complaints are actually caused by emotional problems.

She does not want to see a doctor. She has become very fearful and child-like. She doesn't want to be left alone for even an hour. She lives a few miles from us and frequently stays the night with us. But she calls me to she has no where to go in the evening and doesn't want to be alone because she doesn't feel well. I feel that we must take her wherever we go so she doesn't have to be alone. Either that or just stay home with her.

I waver between guilt/anger all the time. I know I must not be a pleasant companion these days for my husband.
