Depression means feeling low in mood and experiencing several problems like fatigue, reduced motivation, poor concentration, reduced appetite, difficulty sleeping or suicidal thoughts. These might mean you have depression if they've lasted for more than two weeks.

Use the PHQ to see how relevant these are to you.

You might also have noticed some other changes, such as:

• Feeling less sociable than usual, or isolating yourself
• Feeling emotionally numb or empty
• Being unusually irritable with others
• Not enjoying things as you usually would
• Feeling guilty, worthless or that you are “not good enough"
• Everything seems more of an effort
• Feeling more tearful than usual
• Reduced interest in sex
• You might have thoughts that life is not worth living or be thinking of suicide
