I am in pretty good spirits right now, in the afterglow of completing a polished draft of my longest work ever. However, I was seeing some mopeyness and doom and gloom elsewhere on the web, so I thought I would post this prayer. It is not original to me: even Wikipedia allows that it dates back to the fifteenth century. This prayer, and the Lady it is addressed to, have always been helpful to me.
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.
