Hi Paula
You mentioned Breastscreen.
I was originally diagnosed through Breastscreen and they provided a Counsellor on the day of all tests before diagnosis. The Counsellor also gave me the My Journey kit once diagnosed.
Perhaps you could ring Breastscreen to speak with one of their counsellors to help put your thoughts into perspective and gather your questions ready for your appointment and ask for the My Journey kit if you don't already have it.
Lack of sleep is not unusual as you come to grips with it all and waiting for appointments.
Don't get caught up in family and friend reactions as it is a lot for them to take in as well as.
Hope that helps and take care
