If she becomes incompetent I would have to make choices for her that she has expressed she does not want. I am not so sure I could handle the guilt about going against her wishes.
Wow, has she always been like that or doesnt she feel well, I just don't understand with such little information. I sure know one thing, I would not go against my Moms wishes so maybe you should get someone else if you can. I know its hard and a long road, I am also a DPOA and Trustee and caring for my mom six years now in my home. Good luck, maybe you have a sibling who will do it, get a lawyer
