sometimes its better to just be there for them.
Tell them you are thinking about them.... and while you realize there is nothing you can do to change things, if they need to talk or help with anything to get through this, all they have to do is ask. Basically, let them know you care.
Sometimes there's nothing to say except for a hug and listen to her.
Give her a cuddle & a hug no words are needed. She will realize it was gods will
"i love you"......& cry together.......no matter how long it takes ;-)
you don't need words...just give her a hug and tell her you're thinking of her.
Just be there for your friend to talk to, whether that's 10 mins from now or 10 months from now.
