Hits you at a point of realization you're lost ,your confused but then again so sure.thats how it makes you feel , it comes and goes like the rushing wind but no matter how fast it was you feel it deep down within you even when you try to pretend it shows up.its scary it's painful it's disappointing it brings you to a point of doubt and feeds your fears and anxiety.oh how we use to know ,do we still know ,am not sure we know, becomes the sort of statement we begin to utter in this state called uncertainty, it distabilizes and causes diversity.
