Need some help, opinions.

The care takers role is a tough one in it self let alone one that is abused. I know I could not do it. I'm disabled and life has its challenges for me but caring for someone who has more needs than I, no. Love has little to do with it but limitations do, she will be better served by professionals. Get the county nurse involved or what ever social service you can to get her help. Possibly a nursing home is what she needs. Possibly tougher decisions need to be made than where you live.
