Buried in Colorado

Kelly is being deployed to Afghanistan tomorrow. He'll be in training for about a month and then gone for at least 6 months. I really don't know how to feel about this. I was so upset before when I thought he was going and then he wasn't going anywhere, and now I'm trying to figure out when to go pick up his horses (I'm the glorified babysitter), get contact info, talk to him again before he leaves in case I don't get to say good-bye...and I really am not sure it's hit me yet.
