When we experience a crisis, what do we do?

A good advice: Do your best and let God take care of the rest. Take one step at a time and do not try to solve your problems hastily and with high stress levels.

Transfer the pressure from yourself to God and thank Him for taking over the main responsibility for you and your problems. Become a partner with Him. Jesus said: 

"Have faith in God."

Mark 11:22 (NKJV)
