I am Mom's only caregiver, have 4 siblings that do not help. She thinks I am someone else, she thinks I am lying to her all the time. She has dementia, but the last 2 months has gone down fast. I am referred to by her as THEY. She wanders where I am when I am sitting next to her, I have cared for her for 3 years 7 days a week. She hit me hard last nite when I was putting her gown on her. She tells me to go find that daughter that takes care of her. I am at my wits end, I need answers. The doctor put her on the Exelon patch thursday but she is worsening every minute. One of my sisters called her this AM and she whispered to her to call the police to get me out of there. She has completely lost it. I need advice.
