For most of my life, I believed in God, and was a devout Christian. Even inadvertently joining a cult, putting my life in danger, did not destroy my faith. What did was recent flashbacks from joining that cult, plus being forced to helplessly watch my niece drop out of high school to join one.
Yesterday, I started obsessing over the 1983 TV movie, "The Day After". It is on YouTube. https://www.youtube.com/watch?v=yif-5cKg1Yo
I watched the excellently crafted explosion scenes, then read about the movie. It was highly controversial, due to its graphic content. Several network executives didn't want it shown, but it's a good thing it was, because President Ronald Reagan was moved to act to end the Cold War as a result.
At the time the movie came out, I was at one of the lowest points of my life. Looking back, I realize it was due to my own ignorance. Joining the cult was a result of my ignorance, too. This movie, as well as numerous other events, is reinforcing to me that it is up to mankind to solve its own problems; no Cosmic Deity will do it for us. That is why I no longer believe in God.
