Well, as I mentioned in another post, today whilst I was at work I experienced the onset of blushing/anxiety and used the "STOP" statement. Then I got up, asked everybody if they wanted a glass of water and took a break from my desk to go get everyone a drink.
It worked well I think for several reasons.
It took me away from the location where my stress level had risen and let me focus on another less stressful thing.
I was doing other people a small favour (getting them a drink) and they acted grateful to me for it (positive feedback - very important!)
The cold water, being in direct contrast to my hot face, helped me take my focus away from my blushing and helped me feel more comfortable.
I'm only on day one of session three so I hope I can find other good distractions for use in a work situation. I've written another post about this on here.
