That's interesting. My brain does the same in terms of attempting to simulate that model of the people, but when it becomes impossible to run the algorithm (too large of a group), instead of just giving up, my brain goes into panic mode. I have found propranolol helps me with many of the physical symptoms that would otherwise dominate.
Years of practice and “This won’t kill me” thinking have helped a lot. Also I watch every single talk I’ve given which is brutal but it lets me improve but also re-affirm I didn’t die…
