Why do stocks make you emotional?

Why do stocks make you emotional? Like, whenever I’m trading money on stocks or even just observing them, I feel emotional sway towards one way or another. And, other people have experienced this as well, and warn that emotional distress happens when you lose or even gain money in a way. Like, even when I was trading digital coins (not standard stocks) with a bot, I in general felt more stressed out, and I didn’t know why. Then, I eventually realized that the stress of trading stocks or coins in general was probably the reason, which weirded me out. So, what are y’all’s thoughts on this?
