I can truly understand your dilema. I hope that your Mother's pain does not accelerate. My brother and I also have our hands full with my Mom, who, just yesterday, fell and received a compression fracture to her right wrist (last year, she broke her left ankle and fractured her right ankle..so she couldn't walk for 6 weeks). We cannot convince her that she should not be living alone any longer...I wish you and your brother the best of luck!!
Peace and blessings
Look For The Good and Praise It!
