Which Right?

Sometimes I wonder whether it is best to do the right thing or what is right by me. The push is still on to do the one thing I really do not wish to do which is go visit a doctor. I already know that I have COPD and it never will get better. I already know that I am way to thin to be healthy for a normal human. I already know that my cigarette habit doesn't help the COPD. So, what the hell do I need a doctor visit for??? I do wish people would realize that I am happy with myself and my life. Isn't that good enough?
