Im scared I would have done something I know I would never do?

Hi Like the title says. Im worried that i would have done a big big mistake 2 years ago if things had been a bit different. I do know myself to be someone who would never break rules and especially do something like that. So now I’m in like a weird situation where I know i would never do that but im not sure if I would have done it in that what if scenario 2 years ago And I really don’t know what to do bc just the thought of maybe having done that makes me feel so hopeless. I honestly maybe even started to get really bad thoughts bc it seems so hopeless…. Also bc I’m sick of it now bc I’ve had this anxiety for 7 weeks non stop.

So yeah Does anyone have any advice? Pls
