The Thought That Isn't You

This is an educational essay for new and expectant parents, and for those who care for them, about perinatal obsessive–compulsive disorder (OCD) — a common, treatable, and widely misunderstood condition in which loving parents are tormented by unwanted, intrusive thoughts, often of harm coming to their child. Part One follows Jane, a composite illustration drawn from the typical pattern of the illness, through the cycle of the ‘hook thought’, rumination, shame, secrecy, and despair — and explains why the horror these thoughts provoke is itself evidence of safety rather than danger. Part Two turns to recovery: understanding OCD as the disease of self-doubt, learning to see thoughts as passing weather rather than facts or intentions, the place of medication (including its use during pregnancy and breastfeeding), and a set of practical, sustainable habits for living well with the condition. It draws on current clinical evidence and on decades of the author’s own lived experience. It is written to reassure, and it is not a substitute for personal medical advice.
