I live 10 minutes from my mother who is in a retirement condominium neighborhood. I have a sibling who lives 2000 miles away and another that is only an hour away. Both of my siblings still work. My mother has just given up driving. I go to her house one day a week to take her to appointments, to get groceries, etc. She wants to know my schedule in case she needs other things. I want to protect this retirement time that I have worked so hard for. Mom doesn't really require much from my other 2 siblings. Help!
