Sabotaging Thought: Oh, no, I’ve messed up on my diet. This is really terrible!

Response: No, it’s not terrible, it’s just a mistake. It’s not a catastrophe, it’s just a mistake. Telling myself that it’s terrible will demoralize me and make it seem like a much bigger deal, and these things will make it harder to get back on track. I just need to label this a mistake and move on.
