Getting drunk every Friday night and thinking that it's normal, only to get mad every Monday, looks normal only because most people are insane. It becomes abnormal when it affects your relationship sand you push people you want away with a smile and cry when they're gone. That's when a person should question her own sanity. If that still doesn't make one question it, then that's a very deep stage of insanity. That's not life. That's the scenario for an apocalyptic movie.
