I'm really sorry to hear about your friend.
When I was in that situation the best thing my best friend did was to not let me push him away. No matter what I did he kept reminding he was there to listen. You can't force someone out of that kind of situation..they need to be ready to.
Be yhere as a friend and show she does have support.
Take care, if you ever need tk talk please feel free to PM me.
