Don, Just take it easy. That is all you can do. I am an Army wife so I understand exactly what you are going through. It sucks. And it sucks even more when they are gone. But just stay positive. He will be back home before you know it. The best advice i can give you is to avoid reading and watching the news about Afghanistan. All it will do is get you worried and worked up for nothing. If your son is married make sure you keep in contact with his wife. Having a good relationship with her will be your best contact to him. And talk to your son. Express your fears and concerns with him. It is better to get things out in the open now and get all your questions answered now while he is still stateside rather than keeping everything bottled up. hang in there. And remember they are trained to go over there. That is their job. He will be fine.
