Hi there
Welcome to "the club". Sorry that you have become a member though. I had the same thing happen. It felt like every time I saw the doctor, things had changed again. I wonder if that is just the nature if the beast at first. And yes, the waiting is dreadful. It's good to plan ahead but be prepared that you will have to take things a day at a time particularly if you are having chemo. You will get lots of support and helpful tips on this site. Try to keep busy and good luck for the 19th. Hang in there.
