One of the benefits to using NLP for anxiety is that it is a self-administered intervention that can be done any time, anywhere. No medication, props, or people are required in order to access it. All you need is an understanding of how to apply the tool, and to remember that it's there when you need it.
Where do you feel the fear? Is it your head? Is it in your chest? Is it in your stomach, or somewhere else? Does it have a color, a shape, or a size? Close your eyes, turn your attention inward. Notice where you're feeling the fear, and assign some attributes to it.
If it's light, you might try making it heavy. Or vice-versa: if it's heavy, make it light. If it is on one side of your body, shift it to the other side. If it's dark, make it light.
If it's in your head, try shifting it down to your chest, or your stomach. Notice how the feeling changes as it moves to each different location. You could even send it into your big toe. What happens when you send it into your big toe? Or even send it into the ground.
Imagine the scene that is causing the fear as an image, and just imagine that there's a little bath stopper at the bottom. Pull the plug and let all the color and emotion drain away.
Then, you could even make the image darker, dimmer, and farther away.
Run this process a few more times if you need to, experimenting with the ways in which you can play with the image.
Notice how even just the act of changing the way you see something changes the way you experience it.
In the same way that you change clothes after coming home from work, imagine peeling the stress off of you and into a place on the ground. Brushing the stress lightly off and away from you with your hand could also be helpful. Then, once you've de-stressed yourself from head to toe, step out of the pile of stress, bag it up, and throw it away.
