I was raised as a Catholic and I'm atheist now with no regrets. My experience of gradually leaving Catholicism and Theism in general wasn't traumatic.

Yeah, sure I had my crisis but nothing really special. It was more of a problem with me being introverted (INFJ, if you know anything about it) that caused my crisis. I had a lot of depression in my early 20s but it was love related issue.

That said, recently I started discovering something that has to do with how my mom raised me when I was really in too young age to remember it now. It has to do something with my everlasting low confidence and social anxiety but that's something I just started to explore through podcasts psychology related.

She messed up with my mind for sure somehow but how I don't know that (yet).
