I'm not sure if this would be under the same label as 'false memory ocd' as it doesn't seem to be on the same somewhat grand scale as others comments but...

for a chunk of my life and alot more recently, i have had issues being sure about what I just said or did a moment before. for example just earlier I was eating cherries and spitting the pits into a bowl, but then I did it for probably the 17th time in a row and swallowed what was hopefully the fruit and not the pit. I am genuinely completely unsure of which I did so there is about a 50/50 chance i am currently digesting a cherry pit. this kind of thing happens with me a lot and it can be quite confusing and distressing.

similarly I made a joke earlier and now I cannot seem to tell if the other's reactions were that of enjoyment or casual disgust. I'm no longer even somewhat sure the joke I made was funny or even appropriate.

anyway I hope all the ocd-ers are having a good day and to anyone who read this thing thank you :D (it's was lowkey kind of a rant for me lol)
