I've cried so much all of my tears are gone

Well, we found out today that two of the girls in our youth group were in an accident last night and Des, the little 10 yr old, is in critical condition. As of 6 hours ago they gave her 24 to live. I'm broken beyond anything I've ever been. I don't understand it...and I cant stop crying. I just don't understand. I've given God a few ultimatums today....and prayed more then I have in a long time. To be honest, I dont know what I will do if that little girl dies. I just dont know. But for now we've rallied together the youth and we've been praying for like 4 hours....I'm now tired and broken and find myself constantly staring into nowhere.....I'm numb. Please pray for this little girl if you get the chance, cuz she really has changed my life. She has undescribable faith and prays for every single person who needs prayer. She always greats me with a smile and hug...and the last time I saw her she was excited to talk to me on Sunday.....and now it's sunday....and she's laying in a hospital bed in Calgary....I dont know if I'll ever get to talk to her here on this earth again......I'm trying to have the faith of a mustard seed. I'm trying to stay confidant in my God...but what if His plans aren't to heal her??? I won't understand.....and I"m scared of that....but mostly I'm just broken.

These two sisters' parents aren't Christians so if you, her family in Christ, could pray for her that would mean the world to me.
