Does this happen to you?

When an intrusive thought comes I can’t just say “that’s not true” and just move on. I always feel like I have to disprove the thought and be able to say it with confidence but the problem is that the ocd doesn’t allow me to feel and say it with confidence so I get stuck for hours or even days. How can I stop feeling like I need to do this?

I went to bed one night in November, and I can't quite say what happened, but I believed that I had a "memory" from childhood. I won't discuss what, but I had "remembered" doing something sickeningly awful. This thing came to me almost as clear as a real memory. I remember thinking something along the lines of 'How could I forget doing something like that?' followed by a feeling of complete horror and terror. I have moments of "clarity" where I can't believe that I'm questioning doing this thing, and it appears obvious that it's false. But now, I'm more than often believing that I did. I am spending 24/7 fighting my head, and it's taking me to dark places. I know this is the worst thing to do, but you don't understand, if this is real then I am a monster and I can't just adopt the 'maybe I did, maybe I didn't approach'. I just can't. I have to know. I'm so scared. My entire life is on the line. I don't have anyone to talk to about this. Literally no one. I feel like I'm insane, like I'm a monster, like I'm hiding my true identity from everyone I love. Does this sound like False Memory? Or am I in denial, trying to convince myself this didn't happen? Why does it feel so real? And why do I have moments of clarity? I also had my first nightmare about it last night. Please someone help me.

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?
