I somehow can manage phone calls as long as I have paper and pen to doodle. It might start being a set of short notes about the phone call, and is for noting down what people say, but around the notes I also draw wild doodles during the call, and as long as I can do that I have no problems with listening, understanding, and pushing the anxiety out onto the paper where it doesn’t disturb my call. I never realized it was as simple as having pen and paper handy and had so much trouble avoiding calls.

Advantage: nice drawings are produced. Sometimes I like them so much I copy them onto nicer paper and turn them into a proper colored pencil drawing.
