What to do?

In fact, forgiving yourself is good. Feelings of guilt are useless. And to understand that mistakes happen, this is normal. Awareness is the first part of working on mistakes. It is also useful to realize that miscalculations can be simply pleasant. A vacation without a total loss of awareness is not a slip, but a conscious release of control, but not to a state of chaos. Holidays, when you eat more and tastier for a couple of days, and then calmly return to the regime, this is not a slip, but common sense.
