We all have times when our mood is low, and we feel sad or fed up. Often these feelings happen for a reason and pass on their own.

But if these feelings last for weeks at a time, or become so bad that they interfere with daily life, this might be depression.

• Finding no pleasure in life or things you usually enjoy
• Angry or frustrated over minor things
• A sense of unreality
• No self-confidence or self-esteem
