Bottling up your anger may seem like the noble thing to do, but those feelings are energy—and they always wind up going somewhere. Instead of letting them manifest into physical symptoms like another cough or cold, get into dialogue about what's bugging you. A trusted confidante can help you get to the source of the anger: being too agreeable and not asking people to pull their weight. Punch a pillow, hit the gym for a vigorous workout, go for a run in the park. You'll want to move this out of your body BEFORE you have the talk with the offending party.
