Depression is more than simply feeling unhappy or fed up for a few days.
Depression is a low mood that lasts for weeks or months and affects your daily life.
Symptoms of depression include feeling unhappy or hopeless, low self-esteem and finding no pleasure in things you usually enjoy.
Many things can cause depression such as stressful events, personality, family history and giving birth.
Treatment for depression usually involves a combination of lifestyle changes, talking therapies and medicines.
