Replying to MY FRIEND HAS CANCER AT 19??? WHAT THE FUCK AM I SUPPOSED TO DO?

So a few days ago I got some of the worst news I've gotten in my entire life. Jackie, one of my best friends from high school, has ovarian cancer.(Oh, and it was the same day I got the news that my favorite high school teacher died...of cancer) In high school I had a really close knit group of friends in high school of about 14 guys and girls- we hung out pretty much everyday for 3 years, and she was one of the group. So Jackie is 19. I know it seems like anybody would say this about a friend who has cancer, but seriously, she is the nicest, sweetest girl in the world. It's too early to know the longterm prognosis, but I really really hope she will be ok because she would be the best mom in the world, and ovarian cancer could posibly make it impossible for her to have kids. I haven't talked to her about it yet because my friends and I decided not to bombard her with phone calls that would force her to talk about it- she just found out. What am I supposed to do about this? I think i will call her in the next week (I can't go see her, she now lives about 900 miles away), but any prayers would really be appreciated.
