The Catholic Church has always affirmed that every person is assigned a guardian angel. You have an angel specifically assigned to you and that angel's job is to light, guard, rule, and guide.
Matthew 18:10 - "See that you do not despise one of these little ones, for I say to you that their angels in heaven always look upon the face of my heavenly Father."
Pray the guardian angel prayer every day.
Angel of God,
my Guardian dear,
to whom His love commits me here,
ever this day be at my side,
to light and guard,
to rule and guide. Amen.
