Am I depressed or just sad?
Answered by Dr. Nitnem Singh Sodhi · Consultant Psychologist & Psychotherapist · Updated 2026-05-05
Short answer
Sadness is proportionate to a cause and lifts within days to weeks. Depression is persistent for two weeks or more, flattens pleasure (anhedonia), affects sleep, appetite, energy and concentration, and often has no clear trigger. The PHQ-9 is the standard 2-minute check.
Sadness is healthy. It is the mind processing loss, disappointment or change. Depression is a different state — a sustained dampening of mood, energy and pleasure that does not lift on its own and is not always tied to a clear cause.
The two-week rule
If, for two weeks or more, most days, you have either persistently low mood or a loss of interest in things you usually enjoy, plus four or more of: sleep disturbance, appetite change, fatigue, slowed thought or movement, feelings of worthlessness, poor concentration or thoughts of death — that is a depressive episode and it deserves clinical attention.
