One thing I think helps. Focus on today, the moment at hand.
For most of us when this *crap* hits the fan we get wrapped up in a warped sense of psychological time. Everything exists in the past and in the future. Our mistakes of the past. "What will happen" in the future.
This ignores the only real time we have. And that is now.
