Hi there ...and welcome to our little chat room...

Your quite normal .. it happens quite often ... it's like pre grief ... and at first every one is usually in shock .. and the fear of the future gets overwhelming.... 

But knowing that and knowing it's o.k to feel what ever comes into your mind.... it's sure is a rollercoaster ride of emotions ... but once the shock turns in to the "now" please know as someone who has a grade 3 breast cancer... what I tried to do was take each day a day at a time ... not do the "what ifs" and take each day and each problem as and when it comes up ... 

You still have time to make memories and I'm sure she'll need you their for her little one ... you know it's o.k to share tears... admit your both scared... and hold each other's hand .. it will be so so hard .. but trying to get it right now, you'll look back and be glad you did ... every day is a blessing ... I lost my sister 10 months ago ... but we held her hand till the last... that's what sister's do ..

Sending you a vertual hug... hold on in there ... your not alone ... Chrissie x
