My 78-year-old mother has stage 4 kidney cancer and is currently taking Sutent. She is suffering from numerous side effects including nausea, vomiting, loss of appetite, constipation, diarrhea, insomnia, and fatigue. She refuses to allow anyone except my 79-year-old father to care for her. After four weeks of treatment, my father is exhausted, both physically and emotionally. I do not know how much longer he can continue to provide 24/7 care for her. Family and friends are willing to provide meals and respite care, but my mother insists that my father is all she needs. How do I convince her to accept help before I lose both my parents?
