Caring For Aging Parents Support Group
Caring for aging parents can be a difficul time as we become the caretakers for our parents. This broad responsibility can encompass such services as assisted living, adult day care, long term care, nursing homes, hospice care, and in-home care. Whether you have just started caring for your parents or just need a place to talk, we're here.

I am so very sorry for the loss of your father. I lost my father about 2 years ago, and I know how much it can hurt. There are so many things that we need to deal with as we resolve a passing like that. There is a bereavement group here, you can check us out and join if you wish.
As for caring for your mother, that is a very huge undertaking. Having daily care is important if she is not able to care for herself alone. If you believe that to be the case, then by all means get help in to be there with her when you are gone. It can be expensive, but it may be less expensive than a nursing home.
This is a good group for help with dealing with your mother. There are several things that we talk a lot about here, getting power of attorney for health and financial matters is very important, knowing all her meds is critical, and keeping open and honest lines of communication with other family members is also very important.

Though you haven't diverged into details, your consideration of moving her to a nursing home makes me think that she might be suffering from some kind of health issue or illness. If not I would suggest considering an at home care service provider or moving her to an assisted living facility near your location. With home care, you would be able to give her personal attention and keep her near. Whereas in an assisted living, she would meet new people of similar age and get more social interaction, which I feel would be ideal for her considering her current situation and yours too. There are additional benefits as well, such as regular activities and personal care. Staying busy and social could be very beneficial to her healing process and your life as well.
It's best to try not to force any decision on her. First, try to tell her about the difference between living at home and away from home (either assisted living home or nursing home) and ask her to share her thoughts. Consider taking her to tour some local facilities. If you both are not comfortable in talking about all of this then you may want to consider getting the help of another person who is close to both of you and understands you and your mother very well.
I hope this helps. I wish all the best to you and your family.
