No need to get nervous, as it'll do no good for anyone. Relax, and makes lists every day of all the things you will enjoy doing, pain-free, 6 months from now.

As a matter of fact, every day, try to think of any questions you'd like to ask your doctor. Then, when you have a solid list, send it to him/her. I did that when I had my brain surgery, and I was delighted with the surgeons response. He took every question seriously, and watched my reaction carefully to see when it was safe to kid me about a question or answer. Doctors know that, while they may have done this surgery a billion times, this is YOUR first time, and everything is new and scary for you.

Though there are people who swear I do not know the meaning of the word "worry," I do, I just know it doesn't help or hurt, so why do it if you can help it?

Other mind-occuplying activities - look around your place, see what will and won;t be more difficult post-surgery. If you want, I have a friend, Harry, who is currently recovering from knee-replacement surgery, I would be happy to email him for you for a "what to expect" from a realistic viewpoint.
