Depression can be difficult to talk about. Many people go through periods where they feel sad, but when you're depressed you can feel down for several weeks or months.
Depression affects people in different ways and can cause a wide variety of symptoms. They range from persistent feelings of unhappiness to physical symptoms such as tiredness.
It's important to recognise your mental health is as important as your physical health. Those with depression may not be aware of what they're going through and it can become serious if ignored.
