My dad is 83. He been diagonsed with lung and liver cancer. he has refused chemo. They have given him 4 months to live. My mother is 83 and has been ill for years. Dad was her full support. Last night he collasped. she covered him up and sat on the floor with him. Mom wont let me help. Who does she get if this happens again who will be there to do the housework, who will help with the washing, who will cook the meals. Why wont she let me help.
