My 66 year old mother retired last August. She moved in with us at the time. Her job was everything for her and I know it was a transition. I haven't lived with my mother for 20+ years and we were always so close. Since living with us, she is mean and argumentative at times, especially with my son who is 12. She was repeating herself alot. Memory seems intact but she is also hoarding stuff in her room, and refuses to throw things away. I have found an excessive amount of baby wipes, pads, and stashes of snacks in her room. She watches tv all the time in her room and sits in the dark. She is active and going to exercise class daily which she loves. She doesn't seem like "my mom" and I have tried to talk with her multiple times about it. Once she said it was a hard year, another time she said she would talk to the doctor. I hate bringing it up. My aunts thought she was an alcoholic but I don't see her drinking in my house. She also has strange eating habits-eating so much less and eating a ton of pureed foods out of pouches. She was so close to my son and she only argues with him now and never hugs him. I talked to her doctor and he said she was fine. Help!
