I'm so confused!

I knew this day would come when I would have to make a decision on moving my elderly parent out of her home. She is n a rehab and before she is released the doctor's are recommending 24 hr supervision. She and I do not have the resources for this type of care but, she can get up to six hours of home health care. I have 3 sisters and none of them are willing to help. I've argued and fought with them and decided to leave them alone. This would be my world and my world only. My mother has always been strong and independent and loved to keep house. Now, she is depressed because she has lost that independency and would like to go back home and try to live once again. She is a fall risk and does not understand the danger. She is trying to convince me that she would be more careful and will not fall again. She is also stubborn and will not let go.I cannot trust her if she goes home. Also, I have not communicated that much since she's been away because it hurts to much and I don't want to encourage her about her future; I do keep in contact with her staff on her progession. She has some memory loss but, she doesn't understand that someone has to be with her at all times. I want her to return home but, I think of what could possibly go wrong. I still work and I am struggling with that because of depression and anxiety in my own home. My family is no help and it is not fair and my mother does not appreciate them allowing me to take on this by myself. Your feedback on this issue would most helpful.
