I am remembering all of these thoughts from my past and I can't remember which ones are true. How do I stop ruminating??

So, if I'm retelling a story or relaying information to someone, after I'm done speaking, my brain will send me thoughts like, "What if you lied? You might have told the story wrong! You're lying!" I've started second-guessing myself, even when I know I'm not lying or telling the story wrong😭 This has also bled into twisting my intentions behind certain actions... For example, the other day, I'd been babysitting my younger brothers. I'd gone to use the restroom and thought, "What if the door isn't locked or closed all the way?" Because this has happened once in the past. Turns out, it didn't lock correctly, and one of my little brothers almost walked in on me, but luckily, I shut the door in time, and we laughed it off. But then, I kept getting thoughts like, "You knew that would happen, and you didn't double-check! You wanted that to happen and for him to walk in!" :( I know this isn't true, but it's so annoying! Has anyone dealt with this? If you have, do you have any advice on how to deal with these thoughts?

I struggle so bad with intrusive thoughts. They can be so bad that I'll cry because I KNOW that's not how I feel or want to do. (Too embarrassed to say what they're about) I'll constantly try to figure out why I have them, and constantly figure out what they mean, causing me to constantly circle around and around. I had to get on anxeity meds, which helped a little but the thoughts still happen. How do you help yourself with this? How do you know that you're just not some physcopath? 😅

So hard to not engage the thoughts because even though it's from the "past" (i don't even know if im remembering things correctly and it kills me) and i can't change it, I just NEED to prove it to myself that it didn't happen this way. If you'd asked me questions maybe a few months ago, I would have been able to lucidly explain things. Now I just feel like I'm in a constant swarm of thoughts, not knowing if anything is real. If my brain is to be trusted. Wish I could just get hypnosis to forget
