So Close Yet So Far

How does it feel to really want something? To really somehow yearn for that something to the extent it occupies your mind, filling you with it's images until you somehow drown in it? That you were so close to grasping it but it just slipped away? To see it there so near but it will not be yours at that moment? To feel it so real but knowing it's not yours? To virtually hug it but just to wake up realizing its air? Just air?
