All parents know that their children's reaction to events such as their first fall from a tricycle depends largely on how Mom or Dad reacts. All rescue personnel live by the rule to keep calm the injured, the victim, the rescued, etc. Parents and EMTs often fake such calmness. Inside - they're not quite as relaxed.
God, on the other hand, needs no acting skills. He remains undisturbed. Not because He doesn't care. In fact, quite the opposite. He cares and He can handle those events in your life that trouble you - even the ones you cause.
As the angels said to Mary and also to the shepherds, "do not be afraid!"
God does not fret.
