I was in your position just a few short months ago. As I type this I am feeling good today after my first round of chemo last week (although the last week has not been at all fun). My biggest piece of advice to you at the moment is to take every day as it comes. The beginning all happens so quickly and it is hard to take it all in. Then the waiting starts, waiting to heal, waiting for appointments etc.... Then it all happens quickly again. Thinking too much about the next step (in those waiting moments) is not at all good for a positive mindset. Use those days to do things you enjoy so that there are some positive memories associated with those days. I caught up with friends, had some lovely dinners, spent time with my kids.....
I am now going to enjoy the next two weeks before chemo hits again!
Take care of yourself first!
