For me, it feels like I've fallen face flat into a puddle of doubt. Yes, believing in some particular idea and putting it to practice felt great at the time, but now the science has said it's bullshit and I'm wrong for believing in it. If I choose to keep believing in it because it makes me feel good, they're going to call me stupid and a science denier!

Half joking. I'd rather be stupid, get my sleep, and feel great. ;)
