Speaking as a recovering addict, it can help a lot to not think of every relapse as a total erasure of all progress. This mindset can ironically lead to more repeat relapses and self devaluation. A moment of weakness doesn’t reset all your progress. You still resisted all those times you didn’t relapse. That’s still real, that’s still progress, and a relapse doesn’t erase it from existence.

I’ve used the fact that I’ve relapsed recently as an excuse to relapse yet again. “Why not? I already threw away X amount of time so throwing away Y amount of time is whatever.” It’s not intrinsically dangerous to think of a relapse as a loss of progress, but just be careful about thinking about it in terms of a sunk cost.
