Welcome! I was raised Pentecostal and really, really believed. I didn't go straight to atheist, but after I gave up on the Bible being inspired by God, I still had anxiety over my previous beliefs similar to what you describe. It diminished over time and now it really never occurs to me. I had open heart surgery 20 years ago and God never crossed my mind until the hospital chaplain came around afterwards to check on me and see if I needed any prayin'. I had been an outright agnostic atheist around five years at that point.
I'm not anti-Christian. I'm anti-stupid.
