If nothing matters, in what sense is panic the "correct" response? Also, it's useful to check whether you're absolutely doomed to lose everything you value, or only probably doomed to lose most of the things that you value, in situations where you appear to be doomed. I don't think a panic response is generally helpful towards the goal of "make the best you can of a bad situation".
