(20)Sometimes at work, you feel angry or distressed and lose your calmness, snapping at your colleagues or wanting to burst into tears. How can you remove your feelings before you act on them?
    When you are losing control emotionally, it’s hard to step back and see what’s really happening, says Lynn, a psychologist. When you feel an intense reaction at work, ask yourself if it’s realistic and reasonable.(21)Sometimes what’s driving those intense feelings has little to do with what’s happening at the time. " It could have more to do with your professional relationship with this person, circumstances that led up to this upsetting event, self-confidence—or it could spring from earlier life experiences," Dr. Friedman says.
    Rather than reacting in the moment, buy yourself some time by saying: " This is disappointing to me and I want to think about it. Can we talk about it in a day or two?" Then try to look at what is angering and upsetting you as objectively as possible. "If, for example, you’re very disappointed about a decision affecting a project of yours, think about what might be behind that decision," Dr. Friedman says.
     (22)It might help to vent by writing down your feelings and thoughts, says Deborah, founder of Elevated Training in N. Y. The writing process may help you resolve your feelings—and you may want to share what you’ve written with friend, or someone at work you trust. "That person can read it and tell you if they see something in the situation you aren’t seeing," Ms. Riegel says.
