A mood disorder is a mental illness that is made up of various symptoms. Three common types of mood disorders are depression, manic depression (also called bipolar disorder), and affective instability. Depression has one phase (with "depressive" symptoms), while manic depression has two phases (with "depressive" and "manic" symptoms). Affective instability, on the other hand, is comprised of many rapid mood changes.

Depressive symptoms include:

• Sadness
• Loss of interest in activities
• Weight fluctuations
• Sleep disturbances
• Fatigue or feeling slowed down
• Feelings of worthlessness or guilt
• Lack of concentration
• Thoughts of death or suicide
