The thing about changing from one epistemological worldview to another entirely different epistemological worldview is that it's hard to imagine what good looks like.
Imagine, if you can, rebuilding the way you think about even the most fundamental aspects of the world as you know it - teetering on the edge of nihilism since it seems like the only viable alternative.
Hindsight is everything here, but if I could go back about 9 years and explain to the me that was experiencing the crisis of faith I experienced how much better my life would be without all the guilt, shame, confusion, and self doubt that were intrinsic parts of my life at the time I think it would have been an easier road - as it was, I spent two years a suicidal and severely depressed mess - barely surviving the entire ordeal and barely keeping my new marriage intact.
I was probably 19 when it started, I finally came out of it at around 21 (my doubt phase that is). I'm 28 now and I still suffer from occasional mental breakdowns if I hear certain songs, verses spoken, or expose myself to the wrong types of people. The scars I have from my religious past are incredibly deep and I don't know that I could have convinced that young man that it was going to get better - but I know that it does, even if it doesn't all-together go away.
