Depression is a very common illness and can affect people in different ways. Some people suffer long lasting feelings of sadness and hopelessness, while others lose interest in things that they used to enjoy.
Everyone experiences days when they feel a bit down, but if you have those feelings every day for more than two weeks, without a particular cause, it may be depression. You can read more about depression on the NHS choices website.
If you think you may be depressed, contact your local GP for advice about mental wellbeing and the services available to you.
What are the symptoms?
There are many symptoms of depression, including low mood, feelings of hopelessness, low self-esteem, lethargy and sleep problems. The more symptoms someone has, the more likely they are to be depressed.
The treatment you receive will depend on the severity of your condition. If you have mild depression, lifestyle measures such as exercise and self-help groups may be offered to you. Talking therapies such as cognitive behavioural therapy (CBT) are often used to treat mild to moderate depression. In some cases, you could be prescribed antidepressants.
