Avoid circumstances that trigger unwanted emotions. If you know that you’re most likely to get angry when you’re in a hurry then don’t leave things for the last minute. Get out of the house or office 10 minutes before you need to, and you won’t be bothered so much by pedestrians, cars, or slow elevators. Similarly, if there’s an acquaintance you find completely annoying, then figure out a way to keep from bumping into that person. 

Next, you will need to modify the situation. Perhaps the emotion you’re trying to reduce is disappointment. You’re always hoping, for example, to serve the “perfect” meal for friends and family, but invariably something goes wrong because you’ve aimed too high. Modify the situation by finding recipes that are within your range of ability so that you can pull off the meal. You may not be able to construct the ideal soufflé, but you manage a pretty good frittata. 

Furthermore, try to shift your attention. Let’s say that you constantly feel inferior to the people around you who always look great. You’re at the gym, and can’t help but notice the regulars on the weight machines who manage to lift three times as much as you can. Drawn to them like a magnet, you can’t help but watch with wonder and envy at what they’re able to accomplish. Shifting your focus away from them and onto your fellow gym rats who pack less punch will help you feel more confident about your own abilities. Even better, focus on what you’re doing, and in the process, you’ll eventually gain some of the strength you desire.

You can also try changing your thoughts. At the core of our deepest emotions are the beliefs that drive them. You feel sad when you believe to have lost something, anger when you decide that an important goal is thwarted, and happy anticipation when you believe something good is coming your way. By changing your thoughts you may not be able to change the situation but you can at least change the way you believe the situation is affecting you. People with social anxiety disorder may believe that they’ll make fools of themselves in front of others for their social gaffes. They can be helped to relax by interventions that help them recognize that people don’t judge them as harshly as they believe. 

Finally, change your response. Your heart may be beating out a steady drumroll of unpleasant sensations when you’re made to be anxious or angry. Take deep breaths and perhaps close your eyes in order to calm yourself down. Similarly, if you can’t stop laughing when everyone else seems serious or sad, gather your inner resources and force yourself at least to change your facial expression if not your mood.
