One of the chapters of my memoir, Beyond Blue, is called “The Least Harmful Addiction.” I explain that willpower is, regrettably, a finite thing. We have a limited amount, so we must preserve it for the most harmful addictions we have (i.e., when desperate, we should inhale chocolate truffles over getting wasted on vodka). In that chapter, I list all my vices in order of most threatening to least threatening: depression, alcoholism, toxic relationships, workaholism, nicotine, sugar, and caffeine.
Someone in Group Beyond Blue, the online support group I moderate, was reading my book and was confused why I would list depression among my addictions. “Is depression really an addiction?” she asked. Her query inspired an interesting conversation in the group.
