It's good to hear from you, Rick. It's normal to be scared out of your wits before surgery, especially if you have not undergone major surgery before. Catching prostate cancer early is important, so you're in good shape there.
Try to get yourself in as good a shape as you can prior to surgery, especially abdominal exercises. Personally, I used a combination of changing my thought pattern, talking to others who cared, and prayer to alleviate my fears of surgery (my prostatectomy was the first major surgery I had undergone) . It all helped to take the edge off the anxiety.
There's no way around it--a prostate cancer diagnosis and its treatment is difficult to cope with. Take care and hang in there...Tim
