Husband is leaving me

My husband is leaving me in 6 days to go to Bootcamp. I know, click bait title. I thought I'd be prepared, but I'm not. Our son is 6 months and by the time he will get back home our son will be 1. I don't know how I'm going to make it without him honestly. We haven't spent much time away from each other since meeting. Maybe a week at most, but we texted and called the entire time. I have been calm up until now. How have you ladies dealt with it? How do you get through it and make the time fly by?
