During a depressive episode, a person experiences a depressed mood (feeling sad, irritable, or empty). They may feel a loss of pleasure or interest in activities.

A depressive episode differs from normal emotional fluctuations. Depressed mood occurs almost every day, for most of the day, and lasts for at least two weeks.

There are other symptoms, which may include:
Difficulty concentrating
Excessive guilt or low self-worth
Feelings of hopelessness about the future
Thoughts of death or suicide
Sleep disturbances
Changes in appetite or weight
Feeling very tired or lacking energy
Depression can create difficulties in various aspects of life, including community and family, work, and school.
Depressive episodes can be classified as mild, moderate, or severe, depending on the number and severity of symptoms and their impact on personal functioning.
