i think that rumination itself is a sort of autonomic response that's still trying to resolve. It doesn't really get you anywhere no matter how long you do it, but ruminating eventually just tires you out to a point where you're able to work with it.
Legitimatelly sitting in it like you would in water that's just a little to hot or cold for your comfort is probably the way to go, but the water still needs to be in that zone where you can work with it 🙂
