I felt like I was missing something every day. I counted that I had 12 different appointments for tests and the dates and times kept changing so I feared I dropped one or asked for the wrong test. As it happenned I got every last test correct, but the surgeon decided on another at the last minute. Grrrr.
Because of my surgery being 20 years ago and the fact I had a couple of huge risk factors, Doc said I had about a 1 in 20 chance of dying on the table. In fact, his last words when we talked just before surgery were "You know you can die from this surgery?" Yes. "Do you wish to continue?" Yes.
I never worried about my recovery but I did research complications and visualized how I would deal with them. I had an 'open' surgery, meaning they openned me up from stem to stern and closed me up with 30+ staples and a drain. Every little movement was exruciating pain. I knew this was a short term thing and the staples would come out at 4 weeks or so. I told myself I could do anything for 4 weeks. Pain meant eating (puree) and drinking were impossible but I kept trying. Always keep trying.
As I said, I prepared by knowing what could go wrong and mentally preparing for it. Knowledge, for me, is power. Just focus on doing the best you can. Don't kick yourself for what you can't do or do wrong, it's part of being human.
If you have a rough time, it's just the price of admission. If it's easy take the W and keep going.
Success starts and ends in the mind.
Good luck,
