closure.
it's one of those small words that that's been over-used and attached too much importance it becomes a big word.
it's iffy too, you don't really know what IS closure. you think there're certain things you need to do or say or hear someone say to obtain closure, but when that's said and done, it doesn't make you feel any better. and you try to seek closure yet again. it's a vicious cycle.
stop thinking. stop searching. just try and be sane.
