So it getting closer and I'm having all kinds of second thoughts like maybe its all just in my head....although my doctor has recommended this for years, and my ability to do things I love (hike, dance, go up and down stairs) has become seriously limited. On the plus side I'm healthy, dont smoke and am in pretty good shape (swimming, weight training). BUT I live alone (family nearby) and I'm self-employed--which means no sick leave. I have saved about 1 month of salary, but after that I will need to go back to work. Advice please!
