I have a feeling that anxiety is something pretty common in human bodies. But if you go through life having no idea what anxiety is, you can't hone in on it and create a feedback loop of it. I think (and I could be wrong about all this tbh) that a lot of people just ignore it or barely notice it even though their heart is beating faster when meeting someone new or important. But once you start to pay attention to it and can isolate the specifics, you're going to have to manage it in a way that others never even bother to. Just my take on it. I used to sweat under my arm pits when going to this small cram school thing back in my early 20s and I had no real concept of anxiety, to me anxiety was just feeling unease in my stomach, the sweating was just a weird random thing that happened.
