My mother-ion-law lives with us. She has the beginnings of Altzheimer's. She has become very moody lately, and throws a strop when she doesn't get her own way, and stops eating. She literally stays in her room all day like a sulky teenager. We love her dearly, and our caring for her is not just out of a sense of duty. I love her and care for her more than her own daughter does. She finds fault with EVERYTHING! I am at my wit's end. I am a nice person by nature, and I hate conflict, but the nicer I am to her the more it seems to irritate her. I don't know what to do. She has barely spoken to me, and has hardly eaten for about 3 days now. I am very worried.
