does anyone else feel like their obsession turned “real” after something happens? and they feel the need to recheck and recheck over and over that it didn’t?

Does anyone else’s false memory intrusive thoughts of what could have happened feel very, very real?

How do you know the difference :( I genuinely cannot keep living in this torment. it all started with an ‘intrusive thought’ where I had like a hazy flash of something reading an article. and I remember thinking ‘what if’ and ‘what is this’ and then that intrusive thought turned into me ‘remembering’ something else. which caused me panic. then I started trying to find evidence because it contradicted what I remembered this entire time. this was last year in like september. fast forward to march this year, it came back up- but this time stronger and with more ‘details’ and what nots. and I’ve been ruminating on it since then trying to remember and connect and It’s like I’ve added all of these details. but are they real? or is this just my OCD? I just feel like if it were real I would have never been able to keep it to myself. but also what if it was so traumatic that I blocked it out? because it all makes NO sense for me to do something like that. but it also fits what I was thinking at the time. idk

Whenever anyone starts to feel like their thoughts are less triggering or they feel a moment of happiness/ relief OCD tells you that you want the thoughts back or you actually like having the thoughts and maybe thats just the person I really am? I feel like im going insane😢
