Motivation/Military Spouses

For the first time, I'm having a serious lack of motivation after my husband leaving for deployment. This is very out of character for me in that I've always been very independent and we've been separated many, many times before (just never while I've been dieting). I'm not feeling depressed or anything, just lazy, bloated and "blah". I'm not very big to begin with (only trying to lose a stubborn 10-15lbs), so I need every workout and low-cal meal I can fit in. I started out strong for many weeks and enjoyed logging my food and weighing in...now I feel indifferent. Any motivation suggestions or encouraging words?
