In the spirit of the prayers on this thread, I'd like to share this prayer to the Virgin Mary:
Remember, Oh most gracious Virgin Mary,
that never was it known, that anyone who fled to thy protection, implored thy help or sought thy intersession, was left unaided.
Inspired by this confidence, I fly to thee, Oh virgins of virgins, my mother, to thee I come, before thee I stand, sinful and sorrowful.
Oh, mother of the word incarnate, despise not our petitions, but in thy mercy hear and answer me.
One of my favorites.
