My mother 93 with dementia sometimes is so nasty to me. She likes to sleep a lot in her recliner in the living room and jumps with every little noise. Then she yells at me, calls me a few choice words and tells me how inconsiderate I am for waking her up. I have to walk through to do laundry, cook, clean etc. Then tells me I do nothing for her. I quit my job to take care of her. I get very upset, my feelings get hurt and in two minutes she forgets the whole thing happened, but I don't. How do you all handle this?
