Helps me sometimes to grab a glass of water and make myself sit down. I count backwards from ten, slowly, checking in with my breath rate during. I also check to see how tense my shoulders are, then pull them down some and relax as much as I can. Slow drink of water.

Also helps to change my circumstances. A shower. Or a walk outside, making sure to check out what is going on up in the sky too.

Can imagine being in an elevator, pressing the down button, all the anxiety diminishing as you ride to your destination. I take a moment to pay attention to my feet, use imagery to ground myself, pull my energy back down and centered.
