One of the simplest things we can do to feel the way we WANT to feel might not actually be tapping...it could be as simple as breathing with some intention.
We forget to breathe deeply, especially when we are stressed.
Given the pace at which life moves, most of us have shifted to shallow, chest breathing, which alone can trigger a stress response and more anxious thoughts as a result. When our breathing becomes shallow, the brain picks up a state of anxiety and starts thinking anxious thoughts merely trying to match the physiology of the body. (It's just doing its job.)
To maximize the benefits of tapping, I find it helpful to shift into the parasympathetic state throughout the day, as often as we remember that we might be in panic-mode and could benefit from slowing down a bit.
Here's a little run down on my favorite technique: box breathing! Use it whenever you find yourself clenching or rushing and report back with what you notice.
