Notice where you are feeling the worry in your body
Imagine that it has a shape and a color. Think about it's shape, texture, size, and colour until you are clear about what it looks like
Then imagine moving it outside of your body, almost as if it's ob a table in front of you so you can look at it.
Imagine wrapping it in a tight call of putty
Throw it away
Then imagine throwing this putty-ball away with great force. If you can include arm movement in throwing it away even better. If you can say out loud 'I banish you from my body!' while throwing the putty call away it will be even more effective
Now notice how you feel
If there is any part of that 'old' feeling left, then repeat the exercise until you cannot remember what you were thinking about
