Quick answer

What is depression?
Depression is a common mental health condition involving a persistent low mood and a loss of interest or pleasure in things you would normally enjoy. It is different from the ordinary ups and downs everyone has — it lasts for weeks or longer and affects how you feel, think, sleep and cope day to day. It is not a sign of weakness, and it is not something you can simply “snap out of”.
Recognising it
Depression can cause:
- a low mood that does not lift, or feeling tearful or empty
- loss of interest or enjoyment in things
- tiredness and low energy
- changes in sleep and appetite
- difficulty concentrating or making decisions
- feelings of worthlessness or guilt
Not everyone has all of these, and they can range from mild to severe.
What helps
Depression is treatable, and there is a lot that can help:
- Talking therapies such as cognitive behavioural therapy (CBT), available through the NHS.
- Lifestyle support — regular activity, a routine, good sleep, and staying connected to others, which all genuinely help.
- Medication — antidepressants help many people, and a GP can discuss whether they might suit you.
Often a combination works best, and finding the right approach can take a little time.
Reaching out
If low mood has lasted more than a couple of weeks or is affecting your life, please talk to a GP. Depression is common and treatable, and asking for help is an important and positive step.

Common questions about depression
- What are the signs of depression?
- Depression can cause a persistent low mood, loss of interest or pleasure in things, tiredness, changes in sleep or appetite, difficulty concentrating, feelings of worthlessness, and a lack of motivation. Symptoms last for weeks or more, rather than passing after a day or two.
- How is depression different from feeling sad?
- Everyone feels low sometimes, and that usually lifts. Depression is more persistent and pervasive — it lasts, affects many areas of life, and can make everyday things feel difficult. If low mood is lasting and getting in the way of life, it is worth seeking help.
- What treatments are available?
- Effective options include talking therapies such as CBT, lifestyle support (exercise, routine, sleep and social connection), and antidepressant medication for some people. A GP can help you choose, and treatments are often combined.
- Does depression get better?
- Yes. Depression is very treatable, and most people improve with the right support. It can take time, and finding the right approach may involve trying more than one thing, but recovery is the expected outcome.
- How do I know if I'm depressed?
- Everyone feels low sometimes, but depression is a low mood or loss of interest that lasts most of the day, nearly every day, for two weeks or more, alongside things like poor sleep, low energy, or feelings of worthlessness. Free self-checks such as the PHQ-9 questionnaire and the NHS mood self-assessment can help you describe how you feel, although they are not a diagnosis. If symptoms persist, see a GP.
- How can I help someone with depression?
- Let them know you are there and willing to listen without judging or rushing to fix things. Gently encourage them to see a GP or refer to NHS talking therapies, and offer practical help such as going along to an appointment. Keep in touch, be patient, and look after yourself too. If they ever mention suicide or self-harm, take it seriously and help them get urgent support.
- What is it like living with someone who has depression?
- It can be hard, and at times lonely, to live with someone who is depressed. Try to be patient, keep gentle routines going, and share small activities without pressure. Encourage treatment and notice small steps forward. Make time for your own rest and support, and consider a carers group. Get urgent help if they talk about not wanting to be alive.
