An internet board of psych dilletantes is probably not the place to asking this question. Do some research on "ennui", which is related to but not the same as depression. There may some recent research on sleep disorders and ennui, so if you have unusual sleep patterns (eg you are always screwing with your circadian rhythms that may be a place to start. If you are still in school a trip to the school psychologist would be my suggestion.
