Rasque

A moment you instantly wish you could take back, feeling a pulse of dead right after crossing a point of no return - a blurted confession, a hurled insult, a final decision you've been debating for months - wanting to take just one step backwards in time, reverting to the way things used to be just minutes ago.

"I was filled with a feeling of rasque as her blank stare showed that what I had said changed things forever."
