My mom has been a widow for 5 years. She is active during the week, but weekends are hard. My sister is no help and I don't have any other family near by. My mom feels lonely since most of her family lives far away and all she has near by is me and my sister. I am still working and I have house chores and errands to do on weekends. How do I balance her needs with mine? She would fill my whole weekend if I let her. I love my mom, but I need some time to take care of my own stuff.
