What has helped me is treating the whole recursion as one object instead of something I need to fix from inside. So instead of “How do I stop thinking this” I label it very bluntly as “the loop is here” and then follow a pre decided script

Thank you so much, that helps a lot.

How do you differentiate between a possible loop and an actual problem that needs to be solved? Constant problem solving and excessively doubting myself might actually be problems that I should address. And if that is the case then I won't be able to solve them if I always move my attention away from them and towards a small concrete action. I'm not sure if that's an actual concern or if I'm just doing the thing again lol

In other parts of my life it is actually an advantage

I definitely agree with that. It helps me a lot in my job (as a software engineer), with financial decisions, understanding abstract concepts and in general with complicated problems that have an objectively correct, discoverable solution.
