Depression is a common condition that will affect one in three people at some time in their life. It is a complicated de-habilitating illness with many different symptoms and causes.
Changes in eating habits, sleeping patterns and overwhelming feelings of despair are often the first signs. Many sufferers become emotionally detached from those around them and withdraw into a world of their own. Some describe it like being in a prison with no windows or doors, which can alienate friends and relatives, increasing the isolation.
