Sometiems I get scared to think for too long because I’ll start remembering stuff from the past and ruminating about it

I'm having the hardest time right now with my own ruminating negative thoughts that may or may not possibly come true. I fear the worst and replay what that looks like in my head over and over. The best I can do is my best and wait for the horror to end. I want to cry, but can't. I'm scared and alone in my head. My anxiety is extreme. What should I do in the meantime while I'm going through this? How can I minimize or stop the way I'm feeling? Please, I need help.

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 don’t know how to deal with the thoughts that come and barely gone. Usually, the brain often remembers and forgets things. People with OCD however struggle with trying to forget the intrusive thoughts because of the imbalance trying to convey what is real and if the thoughts in your head will come true. Just for the past few days, I was having fun and suddenly hit with a wave of obsessive thoughts and making me stuck with nowhere to go.
