Act of Contrition
The traditional Act of Contrition taught to generations of American Catholics. Pray it in Confession after you have told your sins, and every night before sleep.

The prayer
O my God, I am heartily sorry for having offended Thee, and I detest all my sins, because I dread the loss of heaven and the pains of hell; but most of all because they offend Thee, my God, who art all good and deserving of all my love.
I firmly resolve, with the help of Thy grace, to confess my sins, to do penance, and to amend my life. Amen.
Pray it this week
Learn it by heart this week by praying it each night at the end of your day.
