Antine with false memories ever get it that you are 95% sure said thought/memory didn't happen but your mind is still convincing you its real

Oh yes indeed! All the time. It seems so real and because the same thought is constantly in your head you think it must be real as it seems so vivid all the time....but it can switch ever so slightly like all of my obsessions have. I will start off worrying if this or that happened in a certain way then it will change ever so slightly saying well did this happen instead! It confuses me so much because if it had happened in the first place there is No way it would change ever so slightly! Just a horrible illness it is. Hope you are Ok x

Exactly!! That is OCD for you. It is a very horrible twisted disorder.

This is exactly what I'm going through. I had an overnight stay with work colleagues and I woke up thinking I'd cheated on my partner. I have ruminated for months now and its changed I.e thinking i cheated in the nightclub, then thinking I'd cheated in the hotel room, the person changed etc

you would like to think someone would remember cheating...alcohol or not

There's no way you can have 100% certainty. You have to live your life (as hard as it may be), and pretend there's nothing to worry about. If you're ever confronted on this false memory and told it was real - then you can react/deal with it. You might feel like you're living a lie, but if you want to be happy you have no choice. I have this very type of OCD and it's hell, but you can do it - we all can.

I know you can never be 100% certain but when you think of things logically vs not logical, sometimes the thoughts just seem plain stupid. Of course this doesn't matter because OCD will always cause doubt. Just with me, my theme is always the worst case scenario, and that scenario changes the more I think about it.
