PurrPurr,
To go from faith to no faith is painful. It is like recognizing the hypocrisy of your parents for the first time...devastating.
There are many on this forum that have simply repositioned their faith. For some, that is a viable option. Some people need to "believe" in something. Others, like the humanists on the forum, recognize the importance of living a good life, a good virtuous life, without the constraints of organized religion or some creed to hold onto.
I, like you, was lost. The realization that it was all a sham led me down a very depressing pathway toward self-destruction. Fortunately, I recognized what was happening before I made any irreversible moves or actions. When I did, I came to realize that I didn't need faith, I needed answers. I didn't want religion. I didn't want god or gods. I simply wanted to address the reality of this life.
So, I started searching for answers. I read Hassan's books to determine my programming and combat it. I read Franz' books to justify my realization that it was all malarkey. I read books on philosophy. Books on religion. Books on psychology. Just books.
I came across a book by an author, Stephen Bachelor, entitled Buddhism without Beliefs. It intrigued me. It answered the most important question I had..."Why do we suffer?" It just made sense. By the end of the book, I had come to the realization that the difficulties that we all encounter have plagued mankind since the dawn of time and that no magical "paradise" or "eternal life" was the answer. Those hopes did not address the "now," they served as a bandaid for the open wound that is suffering. When I came to the realization that life is suffering and the kind of life that would help mitigate that suffering, it was an epiphany beyond description. I did not, however, become a Buddhist. I simply began to view life in a different way. It has helped tremendously with the void. It has been both therapeutic and transformative.
Good luck on your journey.
