Writing on Adolescent OCD and Emotional Life

An intrusive thought is not a moral offence, but OCD can make it feel as though it is. For some adolescents, a frightening image or unwanted thought becomes an imagined sin, followed by a private demand for payment: confess, check, avoid, seek reassurance, give something up. This essay considers why the punishment can seem to match the fear, and what may help loosen that cruel logic.

Why does one adolescent become preoccupied with a particular intrusive thought while another fears something entirely different? This piece explores the idea that intrusive thoughts are not random. Their content may gather around what is most emotionally alive, morally charged and developmentally unsettled in the young person’s inner world. Understanding that context can reduce shame and help explain why this thought, for this adolescent, at this moment.

By the time a young person reaches CAMHS, their OCD has usually been described many times. The clinician may know the rituals, the risk concerns and the reassurance being sought at home, yet know very little about the young person. Meltzer helps us think about what enters the room with them: the institution, the pressure for certainty and the fear that an intrusive thought will be treated as a confession. The task is to create an encounter in which thought remains possible.

Why can an old memory suddenly become unbearable in adolescence? Freud’s idea of afterwardsness helps us think about how the past acquires new meaning as the young person develops. In adolescent OCD, an ordinary childhood event may return as moral evidence, inviting review, confession and reassurance. The facts may be unchanged, yet the mind meeting them is different. Therapy can help the young person live with uncertainty without forcing the past into a final verdict.

“I can’t reassure them anymore.” “I feel like I’m failing.” Parents of teenagers with OCD say some version of this to me constantly, and none of them are failing. In this post, Marcus Lewton introduces his new book, When Your Teenager’s Mind Gets Loud, and makes the case that NICE guidance on adolescent OCD, unchanged since 2005, leaves parents carrying more than anyone tells them to expect.

In Chapter 13, Closing Reflections, of Intrusive Thoughts and Compulsions in Adolescent OCD, I argued that what mattered most clinically was not the content of an adolescent’s obsessions or compulsions, but the relationship they had with them. Since finishing the book, one question has stayed with me: could this framework apply more broadly? The more I reflect on it, the more cautious I have become

It describes what works. But not when it becomes possible. In the clinic, ERP rarely fails because of effort. It fails when the thought is too close. For some, there is enough distance to approach it. For others, there isn’t. The issue is not motivation. It is whether there is space in the mind for the work to begin.

New OCD treatments appear every decade, but the core clinical patterns have been recognised for over a century.

Repetitive thoughts aren’t always questions—they’re often cries. Listen beyond logic. It’s not about the answer. It’s about the feeling.

What if OCD isn’t one condition, but four psychic positions? A new way to understand rituals, retreat, and recovery in young people.
