The Psych Central Mood Tracker is a powerful and easy-to-use tool that allows you to track your emotions -- or moods -- on a regular basis. Why would you want to do this? By tracking your moods, you may be able to determine (with or without the help of a therapist) situations or times that your mood goes up or down. Such situations are sometimes called triggers. For instance, if you notice you get depressed everytime you visit your parents, that's important information that you can use to help you understand yourself better.
