When Mother Teresa was in great need, and there seemed to be no solution she had a secret Prayer to the Blessed Virgin.
She called this her Quick or Express Novena. Nine Memorares in a row and she always prayed a 10th Memorare in thanksgiving.
The Memorare Prayer:
Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to thy protection, implored thy help or sought thy 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.
