Don, I'm sure you are still in shock. But it WILL get better, as those of us who have been through many of these types of deployments have learned.
Please be sure to tell us here on the board - preferably in a new topic so we'll be sure to find it - where he finally ends up. The Military Barracks Quilt Project, which is a working group on this board, is particularly aimed at one group in Farah, (western) Afghanistan. We want to follow your DS in case he is nearby and we can "cover him with hugs" too.
Not only that, we have a lot of suggestions for care packages to that area for when you are ready to ship them. You might even start getting a box together now, ready to go out the day you have a good address; packages can take up to 3 weeks to arrive there.
Please keep us posted as soon as you hear anything.
Chin up, Dad; he is already covered with prayer.
