Psychotherapy (esp. CBT - cognitive behavioral therapy - and ACT - acceptance commitment therapy) has been very helpful to me to understand how this works. The fun part has been observing how a professional operates and the effects it can have on someone. So I jumped right into psychology studies. It’s fascinating. It helped me understand my behavior further. There are good introductory books such as « Happiness Trap » (this one is about ACT)

Then lots of reading and experimenting. Related thread (and great article from a fellow perfectionist) « Unlearning Perfectionism » https://news.ycombinator.com/item?id=30223559

"How did you deal with perfectionism?" "Well, I started therapy but that wasn't good enough so I became a psychologist and I'm looking for the ultimate solution for it"

Jokes aside, a better understanding of the need for time- and budget-limited solutions, as well as the realization of the maladaptive social origins of this issue have helped me control my perfectionism to an adequate degree.

Haha yeah, the joke’s not completely out of touch.

Fortunately it lead to a « good enough » understanding and mitigation state in my case. Quite similar to yours it seems!
