Finding an outlet for aggressive energy that is physically/mentally demanding and enjoyable is one of the best ways to handle stress, in my experience at least! If you're looking for a sort of "on-the-spot treatment," controlling your breathing helps tremendously. Try doing it even when a situation isn't stressful.

Working out and during the day and meditation at night works wonders for me. Do you do anything to deal with stress right now?

Besides going on a (mainly chocolate) eating binge, whining, and swearing endlessly? Not really.
