how to deal with uncertainty about events you can’t particularly remember

Can someone give tips about living in uncertainty?

im not diagnosed, but these past two days have been terrible. i constantly have this underlying feeling that i might do something that i think is gross and i feel like i can’t do anything on my own because otherwise i might do something wrong. like i feel like i constantly have to be in front of people so that i can make sure of my every action. this is so exhausting and I’m so confused. and like i keep getting terrible images and stuff replaying in my head. i also try to recall what happened but i feel like i have false event too. i used to have religious ocd and that eventually stopped completely, but now it feels like all my work getting over that was pointless. also like i feel like i might have contamination ocd but not the typical germ type. I just get terrible images and I can’t remember if those images are true or not even though they’re impossible and i feel terrible. I don’t know if i could ever get over this because even the thought of it is terrible.

Hi there I talk about religion (but I'm not trying to force it down anyone's throat) So my main event (which is the one that truly bothers me) happened in 2015 when I was 14. I won't go into any details or anything. I will say that it got so bad once that I almost committed something detrimental to my health earlier this year. Not long after that I spoke to a doctor and basically confessed what's been happening to my brain and my mistakes, he mentioned things that really resonated with me, I'll paraphrase a bit: "Okay, so what you did was not good but it's not something to condemn yourself for. It falls into the grey area, you've apologized and have been forgiven (even though I apologized over text, which comes across cowardly)but it seems that you haven't forgiven yourself. There's a whole lot of difference between you at 14 and you at 23. Try to have some perspective." This really helped and it still does, but unfortunately ocd tries to find a way around this. I'll get a thought of "oh but you forgot to mention that other part of the event" and it magnifies it. Can anyone relate? I've done everything but fully move on because I sometimes feel like I don't deserve to move on. And I'm still worried over the future.
