Sam. your friend Brooke is in my thoughts. I had leukemia when I was ten, and the doctors gave my parents very little hope for my survival. Guess what - I'll be 47 in May, and I'm still around to make life difficult for others. One of my best friends died of encephalitis when we were 11. She's still somebody I think of all the time. There is absolutely no way of knowing what will happen, but you can make a big difference by being there for your friend, listening to her hopes and fears. She might survive this, and she might not, but having somebody to talk to honestly can make a very big difference. My impression is that you are a "tough cookie", i.e., somebody who has had a hard life, but is able to deal with adversities. You are going to have be strong for your friend right now, but you have a lot of people right here to fall back on if you're feeling overwhelmed, fearful, discouraged, and so on. Don't hesitate to use personal messaging, or to post problems here.
