Most advice for perfectionists tells you to lower your standards and be kinder to yourself. Reasonable, and rarely enough — because the standard isn’t the root. The anxiety is, and the perfectionism is how it moves through you.
High-functioning anxiety is the hardest kind to catch, precisely because it pays. The reward is real: the results, the reputation, the sense of being on top of it. There’s no obvious failure forcing the issue — until sleep, health, or a relationship is the thing that finally gives.
The work here isn’t to make you less capable. It’s to separate the capability from the anxiety driving it — so the output stops requiring the dread, and you can do the same work without it costing you your nights.
