What is Depression?


Depression is a prolonged sadness, flat or low mood experienced over weeks, months, or years. The nature of depression means it impacts our quality of life and relationships, often daily. It is a common medical condition, with one in seven Australians experiencing depression in their lifetime, and one in 16 Australians currently experiencing depression.

Everyone’s circumstances and experiences are unique, and so the causes of depression will vary for everyone. Life events, personal factors, and biology have all been linked to depression, and it is people’s unique combination of these factors that may lead to the development of depression.

At a simplified and fundamental level, depression is based on the emotions of sadness and motivation whereas anxiety is based on fear or worry and avoidance.
