Really upset

My son is 11 days old and my husband (his father) just left to go back for the rest of his deployment.... we were dual military when we met (I've since gotten out) so I knew what I was getting into its just so hard. He missed the birth by one day due to flight issues getting home and now he's going to miss the next 4-5 months. I'm trying to stay strong for his sake but it's so hard. And now I have to do everything until he gets home....sorry for the ramblings.
