Depression is more than simply feeling unhappy or fed up for a few days. Most people go through periods of feeling down, that Monday morning feeling, but when you are depressed you feel persistently sad for weeks or months. Unfortunately, some people think depression is trivial and not a genuine health problem – it is a real illness with real symptoms and left untreated can lead to premature death.
According to Dr Tim Cantopher, a Consultant Psychiatrist in the UK, in his very readable book “Depressive illness – The Curse of the Strong”, says “depressive illness is not a psychological or emotional state, and it is not a mental illness. It is not a form of madness. It is a physical illness. It is a deficiency of two chemicals that are normally present in the brain – serotonin and noradrenaline. The chemical dopamine and the hormone melatonin are also thought to be involved.”
