There is a richness of thought in certain Jewish books like the Tenach. They have taste and content. In the secular world the appreciation of such books is rare. Instead there is psychology which has no coherent picture of a human being but can make lots of money by the pretense that it does. I think that you might be used to the spiritual content of great books of Torah and perhaps find the secular world a bit shallow when it comes to the understanding of a human being. I recommend finding the great books that would satisfy your soul. I don't say they have to be Jewish.
Plato or Shakespeare might be the right thing for you. Feed yourself on the best and the great thinkers and great spiritual people.
