This powerful prayer to the Virgin Mary was composed by Saint Bernard of Clairvaux in the 12th century. The Virgin Mary never abandons those who have recourse to Her protection.

Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to Thy protection, implored Thy help, or sought Thine intercession was left unaided.
Inspired by this confidence, I fly unto Thee, O Virgin of virgins, my mother; to Thee do I come, before Thee I stand, sinful and sorrowful. O Mother of the Word Incarnate, despise not my petitions, but in Thy mercy hear and answer me.
Amen.
