"Guardian Angel, tutor and my teacher" Prayer to ask for a grace

Prayer to the Guardian Angel
Very kind angel, my guardian, tutor and teacher, my guide and defense, my wise advisor and very faithful friend, I have been recommended to you, for the goodness of the Lord, from the day I was born until the last hour of my life. How much reverence I owe you, knowing that you are everywhere and always close to me!
With how much gratitude I have to thank you for the love you have for me, and how much confidence to know you as my assistant and defender! Teach me, Holy Angel, correct me, protect me, guard me and guide me for the right and safe journey to the Holy City of God.
Don't let me do things that offend your holiness and purity. Present my desires to the Lord, offer him my prayers, show him my miseries and implore me the remedy for them by his infinite goodness and by the maternal intercession of Mary Most Holy your Queen.
Watch when I sleep, support me when I am tired, support me when I am about to fall, stand me when I have fallen, show me the way when I am lost, heartened when I lose heart, illuminate me when I do not see, defend me when I am fighting and especially on the last day of my life, shield me from the devil. Thanks to your defense and your guide, finally obtain me to enter your radiant home, where for all eternity I can express my gratitude and glorify with you the Lord and the Virgin Mary, yours and my Queen. Amen.
