I sure feel your pain. You are doing the right thing. I went through the same thing in 08 with my Dad. He died in a nursing home. 09 my son (22 years old) died of a massive heart attack. No bad habits at all. Fluke. Now I am dealing with my Mom. I hope my sister and I can have the strength to make her last moments on this earth somewhat enjoyable. She is a tough old bird but I can see the end. Take solace in the fact that she has lived a very fruitful life and raised me.....
