A compulsion does not have to involve your hands. Some of the most exhausting OCD rituals happen entirely inside the mind.

In my consultation room, I regularly see clients who have spent a decade believing they were just "overthinkers." They are not. They are doing compulsions. Silent ones.

Mental reviewing of a conversation to check they did not say the wrong thing. Replaying a memory to confirm they are still a good person. Neutralising an intrusive thought with a "safer" one. Silent counting, silent praying, silent reassurance. Googling a symptom one more time for a certainty that never quite lands.

No one around them sees any of it. Often they have not seen it themselves.

This is where shame settles in. If you cannot point to a visible behaviour, it is easy to assume the problem is your personality. That you are weak, anxious, "too much in your head." You are not. You are running a ritual your brain has learned will bring short-term relief and long-term fuel for the cycle. 🧠

Mental compulsions are a real clinical category. They respond to the same evidence-based treatment, Exposure and Response Prevention, as the visible kind. But you cannot treat a loop you have not named.

Giving the behaviour its proper name is often the first thing that changes. Not because the name makes the thoughts disappear, but because it moves the problem out of "something wrong with me" and into "something we know how to treat."

If you recognise yourself in any of this, what would change for you if you stopped calling it overthinking and started calling it what it is?

Why can an ocd thought feel completely true, even when part of you recognises that it is irrational?

ocd can trigger a genuine threat response and then use the resulting anxiety as apparent evidence that something is wrong. Checking, reassurance, and mental review may briefly reduce discomfort, but they can also reinforce the cycle and make doubt return.

Understanding this mechanism can help you recognise an important distinction: the fear may be real, but that does not mean the danger is.

Why Does OCD Feel So Real?

You may recognise that an intrusive thought is irrational, yet it can still feel completely true. Why?

OCD activates a genuine threat response before your rational mind has time to evaluate the situation. Anxiety can then become apparent “evidence”: *I feel frightened, so the danger must be real.*

Checking, reassurance and mental reviewing may provide brief relief, but they can also weaken your confidence and make the doubt return even more strongly.

In my latest article, I explore the mechanisms that make OCD so convincing, introduce the “Conviction Stack”, and share a simple three-question tool for recognising the realness trap.

"This isn't working. It's making me worse."

I hear a version of that sentence in almost every ERP therapy. Usually around session three or four, when the exposures start biting properly and the anxiety climbs instead of settling.

Here is what I want anyone considering ERP, or currently stalling in it, to understand: the discomfort is not a warning sign. It is the mechanism.

Your brain cannot learn that uncertainty is survivable unless it first meets that uncertainty without a ritual to escape it. If the anxiety never rises, the exposure isn't active. Nothing new is being learned. The old loop stays intact.

So when clients tell me the exposure feels unbearable, I don't take that as evidence something has gone wrong. I take it as evidence something is finally going right.

The shift happens the moment a client stops reading rising anxiety as danger and starts reading it as confirmation. Progress stops feeling like endurance. It starts feeling like evidence.

Discomfort in ERP isn't the therapy failing. It's the therapy working.

A repetitive behaviour can look identical from the outside while serving a completely different purpose.

In OCD, it may be a compulsion performed to reduce anxiety or prevent a feared outcome. In autism, it may be a stim that helps regulate sensory or emotional overwhelm. With ADHD, it may provide stimulation or support attention and task completion.

This distinction matters because only the OCD compulsion belongs in an ERP hierarchy. Treating a harmless stim as a compulsion can remove an important coping tool and increase distress.

A useful starting point is to ask what happens when the behaviour is blocked, whether it is wanted, and what purpose it serves. The function—not simply the appearance—should guide treatment.

**OCD, Autism and ADHD: Overlap, Differences and ERP**

A repetitive behaviour can look the same from the outside while serving a completely different purpose.

Is it an OCD compulsion driven by fear? An autistic stim that helps regulate the nervous system? Or an ADHD-related habit that provides stimulation or supports attention?

Understanding the function matters. ERP should target unwanted compulsions—not harmless stims, valued routines or genuine sensory needs.

This article introduces a practical three-question Function Test and explains how ERP can be adapted through concrete language, sensory awareness and ADHD-friendly structure.

A client once told me she spent three years avoiding ERP because she thought it meant being thrown into her worst fear on day one.

It doesn't work like that. And the gap between what people imagine ERP to be and what it actually involves is, in my experience, one of the biggest reasons people delay starting.

Research suggests ERP leads to meaningful symptom reduction in around 60 to 70 percent of people who complete it. But "complete it" is the quiet part. Many people never begin, because the picture in their head is terrifying and inaccurate.

Four things experienced clients often wish they'd known at the start:

It's gradual, not a plunge. ERP is a collaborative hierarchy. You set the pace, I make sure we don't accidentally feed the OCD on the way up.

Anxiety rising isn't a sign it's going wrong. It's the mechanism. We're teaching your brain that the fear can move through you without a compulsion attached.

Mental rituals count too. Reassurance-seeking, mental reviewing, silent reciting, Googling. If we only target the visible compulsions, the loop keeps running underground.

Progress isn't linear. A wobble isn't a relapse. Learning the difference is part of the work, not a detour from it.

Knowing this doesn't make ERP easy. It makes the decision to start an informed one, rather than a frightening one.

"I tried therapy before, but looking back, I don't think they really knew OCD."

I hear a version of that sentence almost every week. Someone spent months, sometimes years, in a therapy room that felt kind and supportive but never touched the thing that was actually running their life.

Choosing an OCD therapist is not the same as choosing a therapist. The clinical difference is measurable, and people deserve to know what to ask.

Three questions I'd want a client to ask before their first session:

Do you use ERP specifically, and how much of my treatment will be built around it? ERP (Exposure and Response Prevention) is the NICE-recommended first-line psychological treatment for OCD. Talking about intrusive thoughts is not the same as treating them. If a therapist describes their approach as "general CBT" or "we'll explore where it comes from," that is a different piece of work.

How do you handle mental compulsions? This is where a lot of well-intentioned therapy quietly goes wrong. Reassurance, mental reviewing, and silent neutralising are compulsions too. A specialist will recognise them in the room and gently decline to feed them, even when the client is asking directly. A generalist often provides the reassurance, and the loop gets stronger.

What does a typical session actually look like? A specialist should be able to describe it plainly. We build a hierarchy together. We do exposures in session and between sessions. We track what the compulsion is doing, not just what the thought is saying. If the answer is vague, that tells you something.

I say this from a position of genuine pride in the field, not to position myself. There are excellent OCD specialists across the UK, and the work they do changes lives. What I want is for the person reading this to walk into their next consultation with better questions than I had access to when I started my own training.

If you've had therapy that didn't touch the OCD, it wasn't your failure. It was often the wrong tool for the condition.

OCPD is often misunderstood as extreme tidiness, organisation or perfectionism. In reality, it is a pervasive pattern of rigidity, control and demanding standards that can affect work, relationships, emotional wellbeing and the ability to adapt.

It is also important to distinguish OCPD from OCD.

Although the behaviours can appear similar, their psychological functions are often different. OCD compulsions are generally performed to neutralise an unwanted fear or intrusive thought. OCPD behaviours are more commonly driven by standards, rules or beliefs that the person experiences as appropriate and necessary.

Treatment is not about asking someone to abandon conscientiousness or become careless. It is about helping them recognise when their strengths have become inflexible—and learning to adjust effort, tolerate uncertainty, delegate, accept “good enough” and act according to broader personal values.

Recognising OCPD can be particularly important when ERP for OCD appears to have stalled. Sometimes perfectionism can take control of the treatment itself, turning exposure into another task that must be completed flawlessly.

The thoughts my clients find hardest to say out loud are often the ones that respond best to treatment.

Harm OCD. POCD. Scrupulosity. Sexual orientation OCD. These subtypes share something specific: the content feels so disturbing that people spend years convinced the thoughts must mean something true about them. So they hide. And the hiding becomes part of the problem.

In my work with clients, I see three reasons shame keeps this stuck:

OCD targets what you value. Intrusive thoughts feel unbearable precisely because they contradict who you are. OCD does not attack things you do not care about.

Concealment is a compulsion. Hiding a thought from your therapist, or from yourself, briefly reduces shame whilst signalling to your brain that the thought is genuinely dangerous. The loop deepens.

Naming is not owning. Saying a thought out loud in ERP does not mean you believe it. It means you are treating it as what it actually is: a thought, not a verdict.

The content that feels most unspeakable is usually the content most worth naming. Getting it into the room is often where treatment begins.
