Depression is a mental health disorder that is characterised by feelings of sadness, anxiety, hopelessness and many other psychological and physical symptoms. Depression can affect people of all ages, genders and backgrounds.
Part of understanding the realities of depression is to get to terms with some of the research and statistics on the topic, separate from general mental health statistics.
