What IF You Couldn't Stop Overthinking?

What if your brain never stopped overthinking? Not at 3 AM. Not over one text. Not ever. One "okay." with a period would ruin your whole morning, choosing between cereal and toast would make you late for school, and "Enjoy your meal!" "You too!" would replay in your head for the next ten years. Follow SPARK through a month of nonstop overthinking: why your brain replays your most embarrassing moments, what the negativity bias and the Zeigarnik effect are, why every choice turns into a boss fight, how the spotlight effect and the liking gap fool you, the science-backed tricks that actually turn the volume down... and the red umbrella that keeps showing up by the front door. What's the dumbest thing you've ever overthought? Tell us in the comments. And who do you think keeps leaving that umbrella?
