Focus externally on other people and other circumstances in your life. Stay away from going into your head and worrying, doubting, and fearing. Focusing externally allows you to calm yourself down and pay attention to the present moment. Focusing externally reduces anxiety and helps us get into the habit of paying attention to other things instead of our internal, negative, irrational thoughts. https://www.socialanxietyinstitute.org/focus-externally
