It really depends upon how much and why I'm stressed.
If its because I'm worried about something or someone, I'll usually pray for a little while and then try to zone out after that. I'll usually do that by reading, usually an old favourite or at least something from a favourite author (like a security blanket

)
If that doesn't work, and I'm completely stressed out, I'll put on a podcast or audiobook and try to catch a nap, if possible. As I tend to lose sleep if I've been worried or tensed a couple hours of sleep usually helps to get the stress down to a manageable level.
If I'm stressed and pissed off, either because of a person or a series of events, I like to try and get rid of some of the anger, preferably not on anyone as I may say something I may regret later. So I usually try to get away from that person or situation,if possible and work off the edge of the anger by physical activities or if that is not possible, by playing a Video game, either a racer or shooter.
If that's not possible, I'll try to get a little peace, by finding a quiet room or corner, plug in my mp3 player and try to think about something else, and try and calm down.
I did use to binge eat when upset or stressed when younger, but it lead to other problems so I try not to do that now. Still a nice drink (non alcoholic ) such as fresh coffee hot or cold, shake, etc. can de stress a bit faster, and often working to make one can help as well.
