I don't have the answer Aleina, and right now, no answer will comfort you. But the Lord is on His throne, and always Sovereign.
It's in these awful times that we must cling to Him the most. Satan waits for us to weaken, to doubt, and then he moves in. For us on the outside looking in, it's so much easier to come up with reasons, but when it's happening in our lives, we loose all understanding.
All I can say right now is to turn it over to the Lord and let Him carry your burden. When you are free of that, then you will be able to minister to your friend. I will be praying for all of you.
God is Good...All the time.
Rejoice in Him always. /
