Public relations is a high stress job with a lot of mental demands. It will help you do better at your job and also help you be a better employee if you pick up some "extracurricular" activities. Sports and hobbies are great places to focus all your work related angst. Sports will help by keeping you fit (which is great for your image) and by giving you a physical release everyday. Lifting paperweights doesn't count as a gym workout. Go to the gym, play racquetball, run, whatever it is you like to do, indulge in it vigorously several times a week. If you don't have any sports try a few out. Your company might have a softball team or maybe your spouse would enjoy bike rides in the evening.
