Hello IWTL,
Well, hurrah for your surgeon who found you the last minute alternative which has turned out to have really good results for you. It sounds as if he has given you good advice - and chemo and rads whilst not the most fun thing you will ever do are completely doable. You are definitely allowed to get upset when the chemo starts, it is a massive thing, but just try to take one day at a time, plan in lovely things to do when you can, and avoid the evil monster Google!
It's hard for you to imagine now, but in a few months this will all be ancient history and you will be looking forward to a healthy future. A little over two years ago, I began this path, and was petrified. My wonderful surgeon has always been straight with me, he cannot give me any guarantees, but he also said to me on the day of my diagnosis, "we will talk about this day in five years time" - so far, so good...
Big hug, and try to enjoy the time between now and chemo as best you can.
