It's my puppy that helps me the most.

Sometimes repeating "In this moment, nothing is wrong," over and over and over until I can breathe again. Sometimes a moment is too long, and I need to bring it down to the second: "In this second, everything is ok. Nothing is wrong in this second."

Breathing. Repeating to myself "In, out, in, out," until the wave of panic or fear or whatever has passed.
