How creative is the art of worrying! A largely baseless concern was filling up every corner of my mind, like poison gas, with worry and fictive worst-case scenarios, making me feel both jittery and paralyzed. My options at these times are 1) petition God, the Tarot, horoscopes or therapists for answers and peace, 2) take a pill, 3) make myself write the Absolute Truth about the concern. Often the resulting draft is an accumulation of put-downs, childish rage, obscenities and rudeness, and if it has potential I try pounding it into shape. If it's a poem I may impose a form on it. I took one such draft and turned it into four-line stanzas of two couplets each, and every stanza had to mention the name "Richard" (a pseudonym for the real name) or a derivative thereof (such as "Keith Richards"). This took all evening. Now that it's polished and disciplined, I lick my chops with delight when I read it.
Baseless worry and catastrophizing are byproducts of a creative mind, so artists often suffer from these mental monsters, which are made up of backed-up, souring creativity. If such a thing is bothering you, write the absolute Truth about it. No one has to see it. Or you may want everyone to see it.
