March 12: Alma 36:21

21 Yea I say unto you, my son, that there could be nothing so exquisite and so bitter as were my pains. Yea, and again I say unto you, my son, that on the other hand, there can be nothing so exquisite and sweet as was my joy.

And that my friends is the real feelings of repentance. Once you experience the Godly sorrow it's hard, but you've got to progress to get to that wonderful, exquisite (yet another AWESOME word-choice in the scriptures (the Lord is a great writer)) joy at the end.
