If you, or others in your group, are prone to panic when stress arises, read this, or have them read this.
It is a simple process and, once learned, it can be applied to everyday life situations too.
S.T.O.P

https://survivalcommonsense.com/stop-and-control-panic/What causes your panic?
Is a bad hangnail distracting you from work? Are you late for an appointment? Missed an important call? Stuck waiting at a stop light? Did you hear loud noises and gunshots from outside? Is someone yelling at you face-to-face? Did the news just announce something which will rock your world? Do you worry about the collapse of world currency? All of these can induce panic reactions.
All of these can benefit from the STOP technique. Yes, some of them require a more immediate action on your part... Don't sit waiting at the stop light after it changes to green and extract yourself from the point of immediate threat. The time needed to run through the four steps' S. T. O. P. can vary, so take what time you need and can safely spend. If necessary, move to a safe spot before beginning the first step; "Stop".
Learn this and make it second nature. Lead others in your group through this process so they learn it too. Training comes first, followed by practice.
Feel free to run about in circles, scream and shout AFTER you have gone through the S.T.O.P. process. If it feels silly to then run, scream or shout, then it worked. If not, STOP and do it again.
