Navigating Doubts vs. True Mistakes in Salah

Salam, everyone. When I'm praying and slip up, I often catch myself stuck between two thoughts: 1. Maybe it's a really tiny error that doesn't ruin the prayer, but then the waswas (whisperings of syaitan) keeps nagging, making me question myself until I fix it just to feel at peace. 2. Or it actually is something that makes the salah invalid, but then the whispering says, 'Leave it, it's fine,' and I end up not correcting it, so the prayer might not count. This happens a lot with tajweed or wudhu steps. You know how it is-you hear so many opinions online saying 'this is wrong, that’s wrong,' and it just adds to the confusion. Any advice on handling this? Jazakallahu khayran for any help or reminders. P.S. I do deal with OCD, which probably makes it tougher.
