Notice your inner "white knuckling".
When things seems out of your control.
Where does it sit in your body?
A collapsing of your chest maybe? A tightness in your throat?
Maybe your jaw is so tight that your teeth hurt or you have a tension headache?
Take a moment to bring it to your awareness.
Then take it for a walk.
Visualizing the tension pouring out of you and into whatever is around you.
A tree, a branch, a leaf, the snow on the ground, rain drops, a puddle, a rock. Whatever you choose.
Take another moment and feel how the tension has melted.
