In some ways, coping mechanisms are kind of like hiccup cures: whatever happens between "feeling crappy" and "feeling better" is said to "work." And many people try an algorithmic approach, only to hate it. The goal is to find something that genuinely reduces the time between feeling crappy and feeling better. That looks different for many people, and most people need multiple techniques.

I like the flowchart; it's similar to how I got over my road rage issues.
