Hi, if you are stressed, or angry because of someone, there are some ways to calm down to help you. Take a deep breath to calm your mind. If it doesn't work, cry out loud, really large, to eliminate all the fatigue in the heart. You can also go chat with friends, chat with people around to relieve stress. But you shouldn't hurt yourself, don't destroy yourself for an unkind person. Don't break things. Deal with your stress in an effective and safe way for yourself
