In the Western world, depression is a serious, life threatening psychological condition that must be treated seriously with a range of medications, counseling techniques and alternative remedies. Suggesting that it is a condition that is all in the mind may promptly earn you a public flogging.
I have been educated for four years in Western psychology and I have lived half of my life with frequent bouts of depression. I therefore should not contradict what the West has to say about depression. A friend however has recently pointed out that depression is an illness of sophisticated people which is probably why I've survived this long. I am not a sophisticated daughter of the privileged West.
In the third world, financial poverty is a natural cure for depression. People are simply just too busy trying to find a way to divert the gastric juices from eating up the stomach walls.
