My last serious episode of delusional thinking is four years behind me. But there are the episodes that foretell psychosis, or even mild psychosis—the episodes in which I must tread carefully to keep myself where I am. When a certain kind of psychic detachment occurs, I retrieve my ribbon; I tie it around my ankle. I tell myself that should delusion come to call, or hallucinations crowd my senses again, I might be able to wrangle sense out of the senseless. I tell myself that if I must live with a slippery mind, I want to know how to tether it too.
