Prayer to recite when you can't keep going

This prayer written by Saint Bernard was recited by many Saints and then there are some testimonies of miracles of some people who recited this prayer with faith and perseverance. God in his ways and times always answers our prayers.

Remember, most holy Virgin Mary,
that has never been heard
that someone appealed
to your protection,
has implored your patronage
and asked for your help,
and remained abandoned.
Backed by this trust,
I turn to you, Mother, Virgin of virgins,
I come to you, contrite sinner,
I bow down to you.
Don't despise my words,
o Mother of the Word,
but benign hear me and hear me.
Amen.
