We all have the blues from time to time, but if you have depression, this feeling is stronger, it affects your thinking and behaviour, and lasts from weeks to months. However, no matter how low you feel, there is hope. There are people who can help you and things you can do to get on the road to recovery.
Depression is very common and can affect anyone, at any age – from childhood through to old age. It’s not a sign of any kind of weakness or fault in you.
About 1 in 6 people experience depression at some time in their life. It affects women more than men, but men seem less likely to recognise the problem and seek help.
Key symptoms include constantly feeling down or hopeless, loss of enjoyment or interest in doing the things you used to enjoy doing, negative thinking and sleep problems. You may even feel so bad that you have thoughts of self-harm or even suicide.
Symptoms can range from mild to severe, and the support and treatment you need will depend on how severe your symptoms are.
Depression can usually be treated with a combination of psychological therapies, lifestyle changes and antidepressant medication.
If you’re depressed, it’s important to get help – the sooner you do, the sooner you'll start to feel better. Remember: there is hope. Many people have come out the other side of depression and have gone on to enjoy happy, healthy lives.
What are the symptoms of depression?
Depression is a change in mood, behaviour and feelings that can be mild, moderate or severe. Symptoms include:
frequently feeling sad and tearful
not wanting to socialise anymore
being unable to enjoy activities that once were fun
poor appetite or overeating
physical symptoms such as pain (eg, headache, back pain)
tiredness and too much or too little sleep
difficulty concentrating and making decisions
difficulty getting much done.
If your depression is more severe, you may also have thoughts of self-harm or suicide. If you have these thoughts, you should get help urgently from your doctor or one of the helplines listed on this page. There are people who can help you get through. Read more about severe depression.
What causes depression?
Sometimes depression appears out of the blue, while at other times something seems to trigger it. The exact cause of depression is unknown but many factors may play a role in depression. For example, you are more likely to experience depression if you:
have someone in your family who has been depressed, such as a parent or sibling
experienced trauma or abuse at an early age
have certain chronic physical health conditions, such as diabetes, cancer, heart disease, Parkinson’s diseaseor coeliac disease, or have had a stroke or have low thyroid hormone

are or have just been pregnant
are an older adult
use alcohol or recreational drugs
are taking certain medicines, such as for blood pressure or hormonal medication.
How is depression diagnosed?
If you are unsure whether you have depression, there are online self-tests you can do, including:
self-test from the Black Dog Institute, Australia.
If you have some, but not necessarily all, the symptoms mentioned above, it’s a good idea to see your doctor. They doctor will ask you questions about your thoughts, feelings and behaviour, including sleeping and eating patterns, as well as how long you have been feeling this way. They will ask if you have had any previous episodes of depression and may ask about what is happening in your life at the moment. He or she may also do a physical examination and blood tests to rule out other causes for your depression.
Your doctor will be assessing not only if you have depression, but what type of depression and whether you have mild, moderate or severe symptoms, as this will affect what treatment they recommend.
What are the different types of depression?
There are several types of depression. You can still be depressed even if you don't meet all the criteria for one of these types. They include:

Depression can usually be effectively treated with a combination of psychological therapy, lifestyle changes and antidepressant medication. For some people, alternative approaches have been useful, such as mindfulness meditation, St John's wort and online tools and courses.
Psychological therapy from a trained professional can help you recover and can reduce the chances of future bouts of depression. If you have depression, especially if it is severe, it’s a good idea to have some form of face to face psychological (talking) therapy. Counselling or psychotherapy can help you with your thinking patterns and anxiety, problem-solving skills and self-esteem, among other things. A number of psychotherapy approaches have been found to be helpful with depression, including cognitive behavioural therapy (CBT). You can ask your GP to recommend someone or find a counsellor yourself.
Looking after your physical health is an important way to improve your mental health. Improvements to four aspects of your daily life can greatly reduce your depression: sleep, exercise, diet and the use of alcohol or other recreational drugs.
Insomnia is closely associated with many mental illnesses, both as a symptom and a potential trigger.
It co-occurs most commonly in major depression with around 80% of people diagnosed with depression experiencing insomnia.
Good sleep can improve your mood and also give you more resources for coping with life’s challenges. Find out about why sleep is important and check out these sleep tips or sleep apps. You could also try SHUTi, an evidence-based CBT programme for insomnia that has been shown to reduce depression (Note: there is a fee). If you are still having problems with your sleep, talk to your doctor about it.
People who are inactive are up to twice as likely to have depressive symptoms than active people. Even one hour of exercise a week has been found to prevent depression.
What we put into our bodies effects not only our physical health, but also our mental wellbeing. A direct link has been found between diet and depression. Find out about healthy eating basics to make sure your diet is providing you with the nutrients to help keep depression at bay.
Alcohol and other recreational drugs
It’s important to avoid using alcohol and other drugs as these can often make depression worse. You may feel like they give you a lift in mood, but the overall effect is to make things worse. Read more about alcohol and mental health.
Antidepressants are generally reserved for people with moderate to severe depression, where psychological therapy and lifestyle changes have not been enough for the depression to go away. They work best when used together with psychological therapy and lifestyle changes.
Antidepressants are not routinely used for people with mild depression, because psychological therapy and lifestyle changes usually work well for mild symptoms. However, if your doctor recommends antidepressants, they will review with you regularly as to how well they are working, whether your dose needs adjusting or you need a different medication, and to work out when you are ready to start coming off them.
There are various classes of antidepressants. The most commonly used antidepressants for first-time treatment are selective serotonin re-uptake inhibitors (or SSRIs), such as citalopram, escitalopram, sertraline and fluoxetine. These work best when used together with psychological therapy and lifestyle changes. Most people will start noticing an improvement within 2 or 3 weeks but it will take 6 months or longer to get the full benefit. If you have troublesome side effects or little improvement in your symptoms after 6 weeks, talk to your doctor about changing the dose or trying a different antidepressant (switching).
It's normal to use antidepressants for up to a year, or longer if you have had depression before. Antidepressants are not addictive but coming off antidepressants should be done slowly, supervised by your doctor, to avoid withdrawal side effects. You should also talk to your doctor if you become pregnant or plan to become pregnant.
Also, check with your doctor or pharmacist before taking any other medicines or supplements – some have interactions with antidepressants that increase the risk of psychological and physical problems, even ones bought over the counter at a pharmacy and some herbal medicines.
Certain complementary therapies may enhance your life and help you to maintain wellbeing. In general, mindfulness, hypnotherapy, yoga, exercise, relaxation, massage, mirimiri and aromatherapy have all been shown to have some effect in alleviating mental distress.
Mindfulness, the practice of being aware of each moment of your day as it happens, has been shown to be effective for some people with depression.You can learn how to do this from online courses such as Breathe or look for a group to go to in your area.
St John’s wort
Research has found that St John's wort is useful in the treatment of mild-to-moderate depression, but not effective in severe depression. The mechanism of action of St John’s wort is not fully understood but it is believed to affect certain chemicals in the body such as serotonin and noradrenaline, and, in this way, is thought to improve mood.
Many of the chemicals in St John's wort interacts with medicines used to treat depression and other illnesses. It is important to let your doctor or pharmacist know if you want to try St John's wort so that he or she can check if it might interfere with other medicines you are taking.
Online tools and courses
