I think that is to one dimensional a view. Many organisms come into situations they are not really fit to survive- society is complex, there are lots of dark corners where specialisation is needed. If you are a social party animal and by inheritance suddenly have to become a 24/7 CEO of a company,without any breaks and non stop political power plays - depression is not indicating that you are unworthy or something. It indicates that you want to migrate in society, away from a unhealthy environment- you detach yourself from the people you have to deal with and wait for reattachment with a better crowd. Sort of the eject capsule from bad influence you do not want to adapt.
