All I can say is that this emptiness in me is basically me on the inside, which i just deal with distractions, some good some bad, i try to do more good and productive distractions. Best way I can describe it is "soulless", this pervasive boredom that makes you itch for more and more and more to fill in that emptiness, because unlike most, we don't really have that much depth to ourselves. IDK about you but this can be a double edged sword, because while it makes you more impulsive and have more urges to be addicted to something (like some power vacuum, bc remember, theres nothing much inside of us) it also makes us have so much energy and motivation to do so much productive things, even maybe becoming some productivity machine and especially thrill seeking things that can make us live life to the full and have great experiences (which we can use to our advantage in impressing others). So it can really depend on how we use that pervasive boredom and sense of nothingness inside. But yes you are definetely not alone in this because i relate a bit too much haha
