My mother is 90 and lives alone. I am her only child and caregiver. Two weeks ago, she misplaced a photo and a letter from her bank. When I came over and found them both, she insisted that I stole them and then put them back. Since then, she has been accusing me of going through her pockets and closet, stealing her money and belongings and enlisting my daughter to help me. When my son tried to speak with her about this, she told him that I had gotten to him as well and he would steal from her, too. I have tried to explain to her that I have never done anything like that ( and never would) but she gave me a searing look and told me that I am a great liar. She has told me that I have "snapped" and am not the same person that I was. This is her behavior. She has told me not to call her and refuses to answer the phone. When I go to her home to bring her groceries, she continues to tell me I am a thief. At the same time, she wants me to take her shopping with me. I really don't want to take her anywhere or spend time with her while she is falsely accusing me of these horrible things. When I call her, visit or take her out, I never know what or whom I am going to get. Is it possible to get her to understand, and how can I handle the stress of dealing with her behavior? I have a full time, stressful job and no one left to help. I thought this would pass but it seems to be getting worse each day.
