>>12149213I think the real way to deal is to chill. Obviously obsessing about it isn't helping as you end up going down a rabbit hole of more and more research. If you are in a class, simply ask a TA or the prof. to clarify. Usually for me it's something related to language, like the question asked or implied something that I didn't notice. I spent like 10 hours going deeper into papers for a question when the answer was so intuitive and simple when I realized it(after a lot of struggle). So it's best to step back and go about your life with the question running in the back of your mind. You will get it.
