False. What you need to do is to relax. Don’t exaggerate or let things get out of hand. Rather than deny these feelings accept them since there times when they will happen and instead try activities that would calm you like reading, walking or even meditating. Don’t dwell on the past because what’s done is done. The best thing to do is to learn from what happened and accept it. Suppressing negative emotions would only take its toll on you and on other people around you.
