I am burning out on the constant problems of mom. Her extreme anxiety, negativity, and almost daily phone calls. She keeps calling asking me to go to bank or make phone call or buy stamps, etc. The stress and constant negativity is affecting my mental and physical health. And how I interact with my husband at times. I am negative myself and am trying to learn a positive attitude. But so much negativity from mom doesnt help. She is 89 years old and has always been rigid. Any positive websites, etc. so I can hear some positivity?
