Don't worry about Rush he has everything in proper perspective.
I understand how he feels. I have a chronic disease and was devastated when I was diagnoised but the doctor let me know that I can function just fine and that other people are a lot worse off than me. He said you can be thankful you don't have cancer etc. And I am thankful and I do function just fine and so will Rush.
I will be waiting for Rush everyday 9A to 12P.
