Sorry to hear of your situation. We prayed with our kids when I found out because my daughter just raised money for some cancer charity and knew that people died from it. I just said that some people die but we are going to pray that I won't die. Then I kept as much as possible for life to be normal. Fellow school mums would help with pick ups and drop offs. Lots of friends and family around which meant lots of time with cousins which they just loved and other kids to play with. Got to church most Sundays. Most teachers were amazed at how well the kids did cope. So it's not all bad. With the chemo I warned them that I would lose my hair and that I'd need to wear a wig and scarves and beanies. I got a great wig and they were happy with that. Protective of me still though. On the whole it was positive then negative.
Hope this helps
