My mother-in-law is becoming increasingly more disagreeable every day. She refuses to take her medicine, refuses to get up out of her rocking chair, refuses to eat (or conversely eats way too much), and screams and yells at my husband (her son) and myself for no good reason at all. (At least in my mind. In her mind I'm sure it's a good reason.) She's been diagnosed with NPH, depression, and diabetes. We go to the doctor monthly, but this month I had to literally drag her to the appointment. We also have three dogs, but she yells and screams at them just like she does with us. I'm at my wit's end. No one else in the family will even talk to her at this point. She and my sister in law disagree with each other so badly that she hasn't seen her grandchildren in almost a year and I know this adds to her depression. I love my mother in law and consider her one of my best friends but I just can't handle her constant anger and bitterness any more. What can I do????
