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 suffering from 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.
