People are prone to overeat or gorge themselves with comfort foods during times of crisis. A helpful tip for those dealing with an emotional crisis: Pick up the phone and call a friend, relative, or a diet counselor and find comfort and solutions there -- rather than picking up the chips and soda.
You'll feel better in both the short and long runs because taking care of yourself is the best way to handle emotional stress. Add something new to your exercise routine too and devote yourself to it. Maybe you've never tried an elliptical machine before (for example).
