Instructive Thoughts Cycle

Advice needed please: Has anybody ever been in a situation where something traumatic or heartbreaking was happening in their life and struggled with rumination? I know there is like a normal amount that you should process something and cry it out but I don’t know that it is conducive to anything to do that on and off for hours? Wouldn’t it at a certain point be considered unhelpful rumination? And if so how does one stop? Because I’m going through something so hurtful and confusing that I don’t know how to stop thinking about it and the usual distractions don’t work for very long. And idk how important this is but it just happened today so it’s very fresh which makes it even harder to not think about and “figure out” why x, y, z happened. Goodness, I’m sorry if I’m weird or a baby

I struggle so bad with intrusive thoughts. They can be so bad that I'll cry because I KNOW that's not how I feel or want to do. (Too embarrassed to say what they're about) I'll constantly try to figure out why I have them, and constantly figure out what they mean, causing me to constantly circle around and around. I had to get on anxeity meds, which helped a little but the thoughts still happen. How do you help yourself with this? How do you know that you're just not some physcopath? 😅

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?
