When things get too overwhelming, I tend to go quiet, like a submarine commander that fears he has been detected by the enemy. Turn the lights out, hold your breath, and wait for the threat to pass.
They teach Naval Aviators to remain calm in the event of a water landing, watching which direction the air bubbles go and then follow them to the surface. So, I’m trying to sit quietly and see which way the air bubbles go so I can find my way.
