About
Your brain predicts disaster. Prove it wrong.
DidntHappen is a worry tracker and anxiety journal that measures the gap between what you fear and what actually happens. Not meditation. Not generic advice. Real evidence from your own life.
Research shows 85-91% of predicted fears never come true (Penn State, 2019). Track your worries and see whether your estimates match reality. Seeing your own numbers makes the pattern harder to ignore.
HOW IT WORKS
LOG - Write a worry. Set a predicted probability (0-100%). Pick a deadline.
WAIT - Your prediction sits untouched.
RESOLVE - Did it happen, partially happen, or not at all?
SEE THE GAP - Your Reality Gap Score tracks every prediction vs every outcome.
