Hi all. What does rumination look and feel like to you?

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?

I find that the intrusive thoughts that hurt me the most are the quiet ones. The ones that, at a glance, can be hard to differentiate from your own thoughts. The louder thoughts are easy to diffuse, to say "maybe, maybe not" to but the quiet ones leave me ruminating for hours trying to figure out if they're mine or OCD's. They leave me feeling disconnected from those around me and even from myself. I can go from happily thinking about marrying my boyfriend in the future to feeling like I have never actually loved him in a matter of minutes all because a thought was a whisper rather than a scream. This is my first post and I'm not sure what I'm looking for in making it. Advice? To know I'm not alone? I guess if there's anything you feel the need to share I'd love to hear it.

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
