There is no easy answer to your question. I think just go with now. Everyone is anxious and frightened pre results after breast cancer so feeling worried and wanting to curl up and hide is normal. However, as you know life goes on regardless. I decided that I would just take each day with what I know. Today you know you have your cancer and nodes out and have completed chemo and still on treatment with Herceptin. Any remaining cells are still being dealt with. You have a loving family and a celebration coming up. Embrace those moments. I found being grateful for being alive right now to celebrate those milestones helped me. I didn't want to miss a moment of my families life. So lovely I would park those dark thoughts, slap on a smile and reconnect in activities with the confidence you are doing everything you can, and whatever the results you will do whatever it takes to continue to be here for your family.
Take care. X
