Feels like a marine's wife

It's been 3 days since my husband left for Houston, Texas. But it feels like forever! He will undergo training, medical and orientation there, then after 7-10 days, he'll fly to Iraq for work. I told myself I won't cry the day we drove to the airport, last Sunday. I cried all my heart out, I already missed him, given it has only been 30minutes since the last time we hugged. I'm so sad, so so so sad. It feels like my heart's breaking into pieces everytime I remember he won't be home for dinner, that no one will annoy me, hug me, kiss me, and the worst is, I'm going to sleep alone in our bed. I don't know what to do for me to get through the day. Hope I would feel better as time goes by. It will be 4-6months, then he'll be back, then another 4months until next year,hopefully sooner than that. I tried shopping the whole day with my mother-in-law for me to forget to be sad, but no, I would be cheating if I say I was ok. Tell me, who'd be sad shopping?? me!

Hope I'd feel better soon, I know this is hard for him too.
