She complains a lot, and when I tell her to quit complaining and try to be more positive, she says I am a bad daughter, that I don't want to listen to her. She lives at her home with my dad. My dad is not the best caregiver, and Mom is mad at him a lot, too. I can understand some of her frustration with him, but why does she get mad at me so much? The big thing she says to me all the time is that I'm disrespectful to her, that she would never say what I say, to her mother...I don't know what I'm saying, other than telling her that she complains too much. I know she is depressed - she sleeps a lot and stays in the bed all day. I am an only child with 3 small children of my own.I don't know what to do or how to handle her. Please help!
