I can't sleep

It's 4am and I have been awake for over an hour. For some reason, I can't sleep. I keep rolling over and reaching for my husband. I guess that's a lost cause for another 12 1/2 months! I am missing him so badly I can't even explain it.
I support our troops all over the world. They are there to help no matter what our government does and no matter who is against them. Even if they seem to lose, they are trying to help the world. Regardless of this, I really want my husband home!!!
He is my best friend and the love of my life!! How can I live without him for so long. It's been about 2 1/2 months and it feels like forever!! This sucks!
The worst part is that the kids miss him and they don't understand why he is gone. They know why but they just don't really understand it. And they definetly don't understand what he is doing over there as a job.
The kids ask questions like, "does daddy have food and water?" "does he have a bed and blankets and a shower?" the best and worse question: "will daddy have scratches and bruises all over when he comes home?" "Why would he have that?" I asked. "isn't he fighting the bad people?" That just led into a whole other discussion. This was from an 8 year old mind you, so I was trying to keep it on 8 year old level. I wanted her to understand but I didn't want to scare her, so I explained that daddy is there more to protect people and he carries a gun. They don't really get into fist fights like you see on tv.
She was temporarily satisfied with that answer. But I know there are more questions like that coming. There always is :)
I can hear the rain outside now. It's romantic... when my husband is home. But for now it just means that everything is wet and the kids will get muddy. I guess that is why there are bathtubs and soap, right? Kids and mud, it just kind of goes together. In the 15 feet from the front door to the car, at least one of my kids will get filthy dirty. I have a garden in front of my house next to the sidewalk going from my front door to my car. As soon as there is water in there 2 of my kids love to stick their hands in there and splash mud!! So lets hope for just one day, I can divert their attention and get them into the car, un-muddied!!

I hope it will be a good day. If my husband calls, I know it will be! I am just on the verge of crying all the time lately so I have to not cry when he calls. It is a morale thing. We have to stay strong if we want them to stay strong. If they know everything is okay here, then they can focus on their job and not worry about us. In Iraq, a preoccupied mind is a dead soldier! We don't want anymore of those!

Well, it's probably not worth it, but I am going to try to get some more sleep.
