Mood swings

Mood swings are periods of rapid changes in mood, ranging from feeling happy, energized, and excited to feeling irritable, anxious, and depressed. They can last from a few minutes to a few days. They can be caused by hormonal changes, stress, or other medical conditions. Symptoms can include feeling overwhelmed, having difficulty concentrating, and changes in sleeping and eating patterns. Mood swings can range from mild to severe and can be triggered by events, people, or thoughts.
