Please can someone answer

Two things are happening: I get thoughts that just keep looping. They almost feel like song stuck in my head. Also, I’ll imagine something and I feel my stomach drop. Then as the seconds go by I keep getting fragments of the this thought but with different details. For example, it’s kinda like how a “vision” is portrayed. I’ll get a glimpse of the thought and then it’ll rapidly expand into something worse every few seconds. I don’t know if I’m causing this or if it’s just an automatic thing like any other intrusive thought. It feels unavoidable, idk if this is a compulsion or if it’s just another manifestation of an intrusive thought. Apart from that remembering an intrusive thought triggers the full thought again and then it just keeps looping or expanding. I don’t know how to stop any of this. Help?

So hard to not engage the thoughts because even though it's from the "past" (i don't even know if im remembering things correctly and it kills me) and i can't change it, I just NEED to prove it to myself that it didn't happen this way. If you'd asked me questions maybe a few months ago, I would have been able to lucidly explain things. Now I just feel like I'm in a constant swarm of thoughts, not knowing if anything is real. If my brain is to be trusted. Wish I could just get hypnosis to forget

Hi all, I’m really grateful for all the support I’ve gotten from people in the last few days. My mental health is at an all time low and I really appreciate the relief people have brought. I had a question about whether an intrusive image of a potentially imagined event can feel just as real as a real memory. I’m doing my best to stop ruminating over an image I have in my head, and have gone so far as requested security footage of myself and have been told both through that and by my friends that nothing bad happened, but the image in my head feels just as real as other memories. I was also drinking the night in question, which makes it harder for me to dismiss the image and makes me feel like I shouldn’t. I was just wondering if imagined images can feel just as real? I’m trying to use tools to ignore the image, and have therapy scheduled for tomorrow, but I feel like I can’t responsibly dismiss the image even with the evidence I’ve gathered if there’s something about a real memory that looks different in the brain and that if so, that suggests my memory is real and I should confess it. I’m really working on stopping reassurance seeking as well, especially now that even after being told that nothing bad happened when the establishment I was at reviewed security footage, my brain is telling me “they’re probably just lying and never reviewed it.” I know I need to just stop ruminating, reassurance seeking, and mentally checking the memory, but I just don’t know if I can/should in case the image is what I should trust more, if that makes sense.
