I think the song is talking about the general idea of forgiving and forgetting. Hence the line "If I don't forget it will kill me... and to stop the remembering." He's saying that it is hard to always forget when you forgive someone. In this song, it sounds like something that is quite difficult to forget. Another idea is similar to smurfpiss. He's talking about how if you let regret and burdens build up without reaching for God, you will lose yourself in regret. That's my basic take. Oh, and the song is awesome!
