I don't know how to help!

I have a friend who doesn't live terribly close to me. We've never been super close, but we've definitely been friends.
She's just suffered through her second miscarriage. I don't know what to say to her. (But, I do know what NOT to say). She's had some infertility testing, and they may have pinpointed part of the reason.
Right now she's angry (not that I blame her). Especially with God. I was so fortunate to have some people who reminded me who He is, and that all things work for Him, even if we don't understand them at the time. And I was able to find comfort in that. I feel horrible, because I want her to have that same comfort. I think, without it, I would have gone insane this last year. When that test came back positive, but the blood test was negative, I wanted to blame someone...who else? But I know He loves me, and He cares for me.
I wish she could see it to. She needs Him now more than ever. Her faith in God will get her through all of this.
If you're reading this, please know I'm not putting your problems "out there". We don't have the same followers, so no one reading this has a clue who I'm talking about. I'm hurting so badly for you right now, and I don't know how to make it better.
