Whenever you realize that the day (or the week, or your life) has gone south, you are allowed to declare that you are starting over from that moment. Just make sure you resolve with a hefty dose of prayer. If you had been doing that in the first place, you probably wouldn't have gotten into such a mess.
I have a friend who, when her kids talk sassy and she has to get onto them and then they are sorrowful for forgetting themselves, says, "Okay. Let's have a do-over." It doesn't erase the sin, nor the earthly consequences, but it does lessen the discouragement.
Jesus did that too. "Neither do I condemn thee. Go, and sin no more."
It is of the Lord's mercies that we are not consumed, because his compassions fail not. They are new every morning: great is thy faithfulness. (Lamentations)
