Here is a wonderful and powerful prayer to St Jude Thaddeus that every Catholic should say in times of difficulties and hopeless cases.
Most holy Apostle, St. Jude, faithful servant and friend of Jesus, the Church honors and invokes you universally, as the patron of hopeless cases, of things almost despaired of. Pray for me, I am so helpless and alone.
Make us I implore you, of that particular privilege given to you, to bring visible and speedy help where help is almost despaired of. Come to my assistance in this great need that I may receive the consolation and help of Heaven in all my necessities, tribulation, and sufferings, particularly (state request) and that I may praise God with you and all the elect forever.
I promise, O blessed St. Jude, to be ever mindful of this great favor, to always honor you as my special and powerful patron, and to gratefully encourage devotion to you. Amen.
Our Father, Who art in Heaven, hallowed be Thy name; Thy Kingdom come,
Thy will be done on earth as it is in Heaven. Give us this day our daily bread;
and forgive us our trespasses as we forgive those who trespass against us;
and lead us not into temptation, but deliver us from evil. Amen.
Hail Mary full of Grace, the Lord is with thee.
Blessed are thou amongst women and blessed is the fruit of thy womb Jesus.
Holy Mary Mother of God,
pray for us sinners now and at the hour of our death
Glory be to the Father and to the Son and to the Holy Spirit.
As it was in the beginning is now, and ever shall be, world without end. Amen.
