I'm so very sad right now.
There is a book I have read called "I'll hold you in heaven".
It breaks my heart to hear about things like this. I will definately keep her and her family in my prayers. I'd just try my hardest to be there for her when she needs someone to talk to. We all know that bottling things up won't help any problem, most of the time it just makes things worse. It does always help me to know that I have people (both online and face to face) that I can talk to that will just listen to me when I need to vent.
I'm so sorry about your friend.
