I also wanted to say this:

I don't think that is a statement or thought that needs reprogramming because well, it is true. You will be sober one day and on that same day have a horrible day. In the same way that I am sure you have been high on a day and also had a horrible day. You can't control reality. It is a shame but it is the truth. Better than trying to reprogram that sentence is to try to get to a point where you can accept it. If you can accept "I can be sober and have a horrible day and survive it sober," then you are good to go.
You are working NA so that should help. For me Buddhist mindfulness techniques have helped. A good book which melds the two is Kevin Griffin's
One Breath at A Time about the intersection between the 12 steps and Buddhism.
