I would add a Prayer to St. Michael the Archangel, too. We can use all the help we can get.
St. Michael, the Archangel, defend us in battle
Be our protection against the wickedness
and snares of the devil;
May God rebuke him, we humbly pray,
and do thou, O Prince of the heavenly host,
by the power of God,
Thrust into hell Satan and all evil spirits
who wander through the world seeking the ruin of souls.
