Depression is a common mental disorder that causes people to experience depressed mood, loss of interest or pleasure, feelings of guilt or low self-worth, disturbed sleep or appetite, low energy, and poor concentration.

​

Depression is different from feeling down or sad.

Unhappiness is something which everyone feels at one time or another, usually due to a particular cause.

A person experiencing depression will experience intense emotions of anxiety, hopelessness, negativity and helplessness, and the feelings stay with them instead of going away.

​

Depression Can Happen To Anyone.

​

Many successful and famous people who seem to have everything going for them battle with this problem. Depression also affects people of every age.  Half of the people who have depression will only experience it once but for the other half it will happen again. The length of time that it takes to recover ranges from around six months to a year or more.

Living with depression is difficult for those who suffer from it and for their family, friends, and colleagues. It can be difficult to know if you are depressed and what you can do about it.

What Leads to Depression? 
 

Depression can happen suddenly as a result of physical illness, experiences dating back to childhood, unemployment, bereavement, family problems or other life-changing events.

Examples of chronic illnesses linked to depression include heart disease, back pain and cancer. Pituitary damage, a treatable condition which frequently follows head injuries, may also lead to depression.

Sometimes, there may be no clear reason for your depression but, whatever the original cause, identifying what may affect how you feel and the things that are likely to trigger depression is an important first step.

​

Types of Depression:
There are several types of depression, some of which are listed below.

​

Mild depression
Depression is described as mild when it has a limited negative effect on your daily life. For example, you may have difficulty concentrating at work or motivating yourself to do the things you normally enjoy.

Major depression
Major depression interferes with an individual’s daily life - with eating, sleeping and other everyday activities. Some people may experience only one episode but it is more common to experience several episodes in a lifetime. It can lead to hospital admission, if the person is so unwell they are at risk of harm to themselves.

Bi-polar disorder
The mood swings in bi-polar disorder can be extreme - from highs, where the individual feels extremely elated and indestructible, to lows, where they may experience complete despair, lethargy and suicidal feelings. Sometimes people have very severe symptoms where they cannot make sense of their world and do things that seem odd or illogical. 

Post-natal depression
Many new mothers experience what are sometimes called 'baby blues' a few days after the birth. These feelings of anxiety and lack of confidence are very distressing but in most cases last only a couple of weeks. Post-natal depression is more intense and lasts longer. It can leave new mothers feeling completely overwhelmed, inadequate and unable to cope. They may have problems sleeping, panic attacks or an intense fear of dying. They may also experience negative feelings towards their child. It affects one in ten mothers and usually begins two to three weeks after the birth.

Seasonal Affective Disorder (SAD)
SAD is associated with the start of winter and can last until spring when longer days bring more daylight. When it is mild, it is sometimes called ‘winter blues’. SAD can make the sufferer feel anxious, stressed and depressed. It may interfere with their moods and with their sleeping and eating patterns.
