One key element is your ability to adapt to the change that brought the stress, whether it was a real event or a negative experience. You might try reinterpreting the situation as a challenge rather than a problem and thereby cope differently. In any case, you have to keep a proper distance from your stress to control it. We are all going to be tested, double-entendre intended. Ultimately the Coronavirus is going to circulate like a seasonal flu but potentially more dangerous and unpredictable. And as a reminder, maintain your social distancing in all situations. Be a little relaxed paranoid; the coronavirus is out to get you. 

Always wear a mask, or you kill the ones you love.
