Take a breath with me before we start. In… and slowly out.
Yesterday you practised the soft no — noticing a thought, and taking one small step back from it. If you tried it even once, you have already begun.
Today we ask a deeper question. Not what your loop is about — but why it keeps running at all. Why it won't stop at a natural ending. Why it has such staying power, returning even when you are exhausted by it.
The answer is surprising. It is not the content of your thoughts that keeps them looping. It is something quieter, underneath — what you believe about the act of thinking them.
Adrian Wells' metacognitive model: it's not the thoughts themselves but beliefs ABOUT thinking that sustain loops
Positive metacognitions: 'worrying keeps me safe / prepared / in control' — these maintain the habit
Negative metacognitions: 'I can't control my thinking' — these increase anxiety and fuel avoidance
Questioning the beliefs about worry is more powerful than questioning the worries themselves
There is a psychologist in Manchester named Adrian Wells who built an entire therapy around this idea, and its results for worry and rumination are some of the strongest we have ever measured.
His insight was this. Underneath your worries, you hold a set of beliefs about worrying itself. He calls them metacognitions — which simply means your beliefs about your own thinking. And these quiet beliefs, more than the worries themselves, are what keep the engine turning.
They come in two kinds.
The first kind sounds helpful. These are the beliefs that tell you worry is useful, necessary, even protective. Listen for whether any of these live in you.
If I worry about this enough, I can stop it from happening.
Going over it again and again helps me understand it.
Worrying shows that I care.
If I imagine the worst, I won't be caught off guard.
These beliefs feel wise. And they are almost entirely untrue. Worry does not prevent bad outcomes — it only makes you live them in advance. Circling a problem does not produce new answers; it produces the same answer, again and again, while the feeling of doing something keeps you circling. Being braced for the worst mostly means suffering the worst before it has even arrived, and often when it never arrives at all.
The second kind of belief sounds frightening. These are the beliefs that your thinking is out of control, or dangerous.
I can't stop once I start.
This worrying is going to harm me.
If I'm thinking this, there must be something wrong with me.
My mind is not under my control.
Do you feel what these do? They create worry about the worrying. A second layer of fear stacked on top of the first. Now you are not only anxious about the problem — you are anxious about your own mind.
Here is the freeing part. Wells found that when people gently question these beliefs about worry — rather than wrestling endlessly with the worries themselves — the loop loosens. In careful trials, a large majority of people improved, often faster than with other approaches. Not by solving every worry. By changing what they believed worrying was for.
You do not have to win the argument inside the loop. You only have to question the belief that keeps you in the argument.
Find a comfortable position · Read slowly
Let's find your belief. Settle, and breathe once, slowly.
Bring to mind the worry you return to most. And instead of thinking about the worry, I want you to look underneath it, and finish two sentences. Take your time. Let the honest answer come, not the polished one.
The first: I keep going over this because I believe that going over it will…
Let whatever comes, come. Maybe: keep me safe. Maybe: help me find the answer. Maybe: stop me being surprised.
And the second: if I stopped worrying about this, I'm afraid that…
Breathe. There is no wrong answer here. You are just meeting the belief that has been running quietly beneath everything.
Now, gently — not harshly — ask it one honest question:
Has worrying about this, even once, ever actually prevented it? Has the loop ever given me an answer that one clear, calm pass of thinking couldn't?
Sit with that. You may feel the belief soften, just slightly, the way a fist loosens when you notice it is clenched.
Your loop is not held together by the problem. It is held together by what you believe worrying will do for you. When you question that quiet belief, you loosen the whole knot.
Tomorrow, we learn one of the most freeing skills there is — how to watch a thought pass by without climbing inside it.
