I'll be keeping her in my thoughts and prayers.
Have lots of positive energy. Keep making sure those around her give her all their love and support is the best you can do.
I remember once on the news, (I think it was in the UK), a group of classmates from some kid who had been diagnosed with leukemia decided to all shave their heads to show their love and support for their friend. That was such a nice thing to do.
I'm very very sorry to hear. While we are mentioning prayers I would like to add a few people to the list if it's ok:
My grampa who we love very much has cancer.
My mum's friend's daughter (who is about 7 or 8) has a brain tumor and cancer. (we haven't heard from them in so long since it happened and I'm not sure how she is doing.)
I will pray for your friend.
My friend had luekimea (sp) for the 3rd time in his life. And he is in healthy condition. So don't worry about your friend. I will love to pray for you friend.
