Is depression mostly physical or psychological?
This is beside the point. There is only one physical you, and only one psychological you. Depression may be triggered by either physical or psychological events. Most commonly, both are usually involved. It is often difficult to separate the two when one is talking about psychology and neurochemistry. Whatever the basis for it is, depression quickly develops into a set of physical and psychological problems which feed on each other and grow. This is why a combination of physical and psychological intervention has been shown to give the best results for many patients, regardless of any diagnosis.
