I'd still argue that a person with "everything going for them" can still have a "reason" to be depressed. Maybe they do a really good duck impression -- calm on the surface, kicking frantically below. That is, maybe there is something wrong with their life or their past that isn't visible to others, or even to themselves. Or maybe they have been pursuing the checklists of society and found that they aren't personally fulfilled by them, and must seek fulfillment elsewhere. Maybe they have a desire to be living one kind of life but can only excel in a different kind of life that only looks good from the outside.
