I’m starting to believe an intrusive thought as a memory and I can’t live with the thought that I might’ve done it ): I know I haven’t but I’m scared I’m going to full on believe I did and ruin my life because of it. No matter how much I tell myself I haven’t I don’t believe it and it feels like my life is over

I keep oscillating between telling myself that a faint memory could’ve been true since it popped into my head in a moment of distress and it was the first immediate memory I had so therefore it must’ve happened, and that I’m just in denial and trying to make it OCD so I can live with the fact that it “might not have happened”. I’m so scared that it did happen and that I’m relying on the fact that I didn’t remember the specifics so that I can have the possibility of it not happening. It’s not something I condone today nor does it reflect who I am nor does it seem like something I would do, but if so, why did it feel so familiar ? I have evidence that my memory is really distorted at times and it combines things and I was in a state of such panic that I might’ve just compiled memories together that is the worse scenario (since it’s something I’m so afraid of happening). But then I keep getting scared that I’m just in denial because I feel a faint familiarity to certain things. I’m honestly so panicked and sad and heartbroken. I keep fearing I did something wrong and faint memories would pop into my head and I would question when it happened and try to remember everything and it would anger me that I couldn’t remember everything. And it feels so wrong for me to just live with the fact that something could’ve happened even though it’s not reflective of who I am today. It feels immoral to not confess. I just want words of comfort and understanding and I just need to know I have hope for the future and I can be happy. Please help.

I don't think I'll ever stop feeling this way. It just keeps coming back over and over again. I keep getting intrusive thoughts that I've sexually assaulted someone and I've ruminated so many times on it that I don't know what to believe anymore. I don't know if an elbow brushing against someone constitutes for that but I'm terrified of it and have been since it happened. Other thoughts keep saying I'm a bad person that's hiding things and I just get drained and defeated from these thoughts. I don't know if I'll ever move on from the past.

Can anyone give any advice please IS IT POSSIBLE TO CONVINCE YOURSELF THAT YOU HAVE DONE SOMETHING THAT YOU HAVEN’T DONE? HOW CAN A THOUGHT/FEELING SEEM SO REAL IF ITS NOT REAL? When you have thoughts/think that you have done something bad in the past to someone ,but you are sure you haven’t and never would. One minute you say to yourself no I would never do such a thing and then you say what if you did as the feelings/thoughts feel so real. The thoughts/feelings sometimes are so convincing you have done something to someone but you truly believe you haven’t , you even question what if there is proof of this happening like recordings and that’s where the constant checking starts. Is this false memory or is it something else?
