I definitely agree, there are two fundamental forms of "depression"--internal and a reaction to a bad external situation. Very different causes, what works for one doesn't work for the other. And I don't even like the "depression" label for bad situations--as with the previous post about willpower. We have a limited ability to cope with bad, when it's exceeded (or our efforts are misapplied resulting in the same end) we get "depression". No, we get reality! That's why things like forcing rehab does nothing about addiction--it doesn't remove what drove the person to the drugs in the first place.
