I can identify with this a lot. I don’t budget as religiously as I used to, but there was a time where I was writing little console apps to process all my recurring stuff and adding one-offs in from a separate file to help project future money. I turned the idea into a website, but really nobody ever used it but me. Shut it down probably a decade ago, and then found YNAB myself, but for the time period it reduced my anxiety by a lot.
