Debbie, I know how you feel. I recently had to by a step stool so Chuck can get up onto my bed at night. I was about in tears when I realized that he couldn't do it by himself anymore. Chuck is 10. It is hard when you realize that you will outlive them but think of it this way, you lived some of the best parts of your life with them. They will never be totally gone.
