I'll bet you are feeling overwhelmed, Annette. This stuff is exhausting and confusing, particularly in the early days. As you start to learn the language and get to know who is who in your cancer zoo some of the confusion abates. It is still a huge thing to deal with and it feels like it takes over your whole life. Unfortunately there aren't many short cuts and we just have to plod through it.
There is a wealth of experience here. There are also no stupid questions and no repercussions if you need to have the sort of rant you may not want to have in front of your family and friends. Good luck. Marg x
