Moodiness and mood swings are states of mind that are familiar to many people. They can occur from time to time and have various causes. They are often part of the normal emotional spectrum we all go through.
Moodiness often takes the form of temporary feelings of dejection, sadness or irritability. It can be triggered by stress, fatigue, personal problems or unpleasant experiences.
Mood swings, on the other hand, are characterised by frequent and unpredictable changes in emotional states. In such cases, people affected swing from extreme euphoria to deep dejection within a short period of time.
