What sucky news to have at this time of year. The good thing it appears that you are a "proactive get all the info I can sort" of person.
Knowledge is power. I would also suggest trying to de-stress your life as much as possible. This will pay huge benefits down the road.
Make sure you stay as upbeat as possible and decrease sugar intake. (No I'm not a vegan, etc)
Stay fit and get plenty of rest. These few suggestions have helped me as I've gone through my trials. I hope they are helpful to you.
May the Lord bless you and keep you in the hollow of his hand. Lynn
