Leo Tolstoy apparently had a similar existential crisis, even to the point of almost ending it all. Maybe reading about his struggle will help some: Leo Tolstoy on Finding Meaning in a Meaningless World - Brain Pickings - Pocket

Despite his observations and insights about humanity and existence, I can't really say anything is resolved. Nonetheless, he lived on for over three more decades after his initial crisis around the age of 50, so I guess he must have found some sort of a solution.
