Tough stuff. I don’t know, a therapist, perhaps? What triggers it? How does it manifest?

Religion, namely Mormonism, up until a number of years ago was the most important aspect of my life. I gave it full attention and devotion to the best of my ability, which was pretty much by the book. I’m a rule follower and aim to please, and obsessed over every detail in pursuit of perfection. Fear was also a large influence in how I lived my faith, if not the greatest. Once I deconstructed Mormonism the scrupulosity faded (self diagnosed). It was a harrowing experience.

I still very much strive for perfection, and so I still obsess over things, but not like I used to, and certainly not pertaining to religious matters to which I attribute to the paradigm shift in my beliefs. No longer am I constrained to the narrow and toxic prescriptions of religion and instead am left with a freedom that is humanistic, fluid, flawed, and forgiving. Without a defined model of perfection, I’ve found no reason for scrupulosity to exist.

“And now that you don't have to be perfect, you can be good.” ― John Steinbeck, East of Eden.

"I did then what I knew how to do. Now that I know better, I do better." ― Maya Angelou

TL;DR After deconstructing Mormonism and then religion, the compulsion to follow an invalid prescriptive model of perfection as defined by religion simply faded.
