Write down positive memories

According to a study, a happy, mentally healthy brain is one that often reflects on experiences that make one feel great and grateful. Redirecting one's thoughts to happier times or memories of good experiences, especially during stressful or depressing times, may show to be a highly effective defense against anxiety and depression.

You've probably received advice to write down positive memories before, but you've never taken it to heart. Give it a serious try right now. Even just setting aside 15 minutes every day to write down memorable experiences you've had with friends and family might help you get over bad moods. You'll be reminded that you're not alone during the process, and the memories will undoubtedly lift your mood.
