hi @Sister
I am going to give you some links to resources available
https//www.mcgrathfoundation.com.au/OurMission/OurNurses/FindANurse.aspx A breast Care Nurse.
My Journey kits and my care kits
https//www.bcna.org.au/resources/On reading your post I immediately thought you had called yourself "sister" in reference to your sister.
It is scary at this stage where you don't know what lies ahead like @Afraser said things have changed heaps since 1999. even in the last few years things are completely different with how Breast Cancers are treated and the survival rates are so much better.
Breathe.....
It's Okay to be afraid to try to hide the fear from the children there are some great resources for kids also at the Cancer Council website.
we understand and get the stress and fear ... feel free to come and rant,cry while typing to us....
I found the shower a great place to have a cry.
hugs
