She is 91 years old. Her only son (my husband) died in Dec. 2013. She can't see and can't walk well at all. Needs someone with her to go to bathroom. I'm feeling guilty about the amount she spends on care and the fact that she's lonely even though she has someone there with her 24 hours a day. My house has steep stairs, and I'm afraid she'll become disoriented at night and fall down the stairs. There's only 1 bedroom upstairs on the main floor, and I would have to sleep downstairs. I really don't want to bring her here (8-hour drive) to stay with me, but I feel guilty. I also cannot make frequent trips to see her because of the distance we live from one another.
