I recommend that you start praying the Divine Mercy chaplet daily. And even if not daily, doing it at least a couple times a week or a decade each day is going to help you a lot. Don’t forget to cross yourself often and maybe bless yourself with holy water if you have it at home. These things have helped me a lot and I know they will help you too.
But above all, if I were you, I would consider my relationship with the Lord carefully. Is work on Sundays an absolute necessity? Are the things that are causing you to get too little sleep necessities? Could you possibly give up some things that cause you to get sleep deprived so that you would be able to go to Mass every Sunday?
I will pray for you.
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. Amen.
I believe in God,
the Father Almighty,
Creator of heaven and earth,
and in Jesus Christ, His only Son, our Lord,
who was conceived by the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
was crucified, died and was buried;
He descended into hell;
on the third day He rose again from the dead;
He ascended into heaven,
and is seated at the right hand of God the Father Almighty;
from there He will come to judge the living and the dead.
I believe in the Holy Spirit,
the Holy Catholic Church,
the communion of Saints,
the forgiveness of sins,
the resurrection of the body,
and life everlasting.
Amen.
Eternal Father, I offer You the Body and Blood, Soul and Divinity of Your dearly beloved Son, Our Lord Jesus Christ, in atonement for our sins and those of the whole world.
