What is the difference between feeling sad and clinical depression?

Depression is more than simply feeling unhappy or fed up for a few days. If you have been feeling persistently sad for more than 2 weeks, have lost interest in things you used to enjoy, feel hopeless, have low energy, difficulty sleeping, changes in appetite, or thoughts of self-harm, you should see your GP. Depression is a real illness with real symptoms — it is not a sign of weakness.

The two-week mark is important. Sadness in response to life events is normal and healthy. But when low mood persists beyond 2 weeks, starts affecting your daily functioning (missing work, not eating, withdrawing from friends), and you cannot identify a clear cause — that is when it may be clinical depression. Please do not hesitate to speak with your GP.

This is an important mental health question. We recommend speaking with your GP for personalised advice.
