MAson, I am so so sorry...I too, hope you can get home as soon as possible, and that God will make your burden more easy to bear. He gives the peace that passes understanding, and I hope you will begin to feel it soon.
Though I am so sorry to hear of your dear Mother's passing, I am glad she was able to go peacefully. My DGM passed in her sleep as well, and I am grateful for that-she wasn't in pain.
You're in my prayers.
