This post is so underrated right now, I hope it'll be noticed more! Great writing but I really liked schematics, helped to imagine how it works. Basing on the definitions You've provided, I can see that what I was calling 'fear' was indeed an anxiety. Oh well, will remember for the next time. And I agree, being exposed to anxiety for too long can be really devastating, I know it first-hand. Thank You, it was an interesting lecture.
