Usually the tragedy is good to give something to keep going, let´s say that X person went to the very bottom of his/her life, all the way to the bottom of the barrel, finally facing reality, the person has nothing else to go deeper and can only go up, the thing that would keep this person from going down is that he/she already knows what lies down there
Have you ever crossed the line between sanity and madness? You would be amazed by what lies beyond the fog..
