We didn't get along great growing up and I feel like she is mostly mean and accusing of me. She calls my daughter and talks bad about me, now my daughter takes her side and isn't talking to me. She tells my brother and anyone who will listen everything is my fault. I moved in with her to help but she says I am trying to take over when I am only trying to help her. Do people with Dementia know to pick on only who they want to?
