Sad news.
I lost my dear stepmum to cancer a few years ago, as soon as she was diagnosed we were told it was terminal and would be weeks. Like Jane her attitude was just to get on, she went back to work and lived a normal life as long as she was able to- for almost a full year. She also encouraged us not to be afraid to talk about it and even after diagnosis there were many good times. Both these ladies showed that even after the worst news you can still do something positive with your life.
To devote your remaining time to so many challenges for other people as Jane did shows a love and compassion for other people which is truly remarkable. She was a real inspiration and I salute the courage of her and her family. May she rest in peace and best wishes to her family, who can be very proud.
