54321 Grounding Technique
Here's a helpful grounding exercise. You can use this if you're having a full-blown panic attack, or when you just feel a tiny hint of anxiety.
You can do this in your head or out loud:
List 5 things you can see, 4 things you can feel, 3 things you can hear, 2 things you can smell, and 1 thing you can taste.
Pay attention to how you felt before, and notice the difference after. It's more effective than you might think!
