My first deployment?

my hubby is about to go on his first deployment, i know the dreading military wife crap of "stay busy", but i'm nervous that i might shut down, anytime my hubby has been gone for more then a week i end up staying in jammy's staying up all night cus i can't sleep, and sleeping until my son comes home from school. but those were just a few weeks, what do i do about an long term deployment? I don't really wanna go see anyone, but could this be a form of depression, even tho i don't feel depressed? i only stay up because i feel scared being alone, which results in sleepiness the next day, and the jammy thang well why dress up when he's gone...right?
