Why do I overthink everything?

Overthinking and rumination are two of the most tiring, under-recognised features of adult anxiety. Both involve the mind looping on the same material without resolution. They look similar from the outside, but they operate differently inside, and the help each needs is slightly different too. This article covers both: what they are, how they differ, how to recognise them in yourself, and what actually loosens the loop.

If you came here searching for help with overthinking, read on. The rumination section further down may be the piece you did not know you were looking for. Many people who describe themselves as overthinkers are in fact caught in a rumination loop, and once that is named, the usual overthinking advice stops bouncing off.

What overthinking actually is

Overthinking is the broad human tendency to go over something repeatedly, usually a decision, a conversation or an uncertainty, without new information coming in. It is often driven by anxiety, perfectionism, high conscientiousness, or a fear of making the wrong choice. The content changes; the pattern repeats.

Overthinking usually feels frustrating rather than catastrophic. You know you are chewing on the same material, and you can sometimes break out of it with distraction, exercise, or a conversation. Mind (2024) describes general overthinking as a widespread experience that responds reasonably well to practical anxiety strategies.

What rumination actually is

Rumination is a specific form of repetitive thought that focuses on the causes, meanings and consequences of distress itself. Rather than solving a problem, rumination circles around the problem looking for someone to blame, a reason it happened, or a hidden implication about you. The classic rumination question is “why did this happen to me?” or “what does this mean about me?” rather than “what will I do next?”.

Nolen-Hoeksema’s research, cited by the Mental Health Foundation (2024), established rumination as a strong predictor of persistent depression and anxiety. It is not neutral thinking. It is a style of thinking that reliably makes low mood and anxiety worse over time.

Overthinking and rumination: the key differences

Both patterns are repetitive, unproductive and tiring. The useful separation is:

• Overthinking tends to be forward-looking: what might go wrong, what should I decide, what will they think.
• Rumination tends to be backward-looking: why did I do that, why did this happen, what does it say about me.
• Overthinking is often anxious. Rumination is often shaped by shame, grief or depression.
• Overthinking responds reasonably to practical anxiety strategies. Rumination usually requires a different approach, including behavioural activation and work on self-criticism.
• Overthinking tends to loosen with distraction. Rumination tends to deepen with introspection, which is why “work it out in your head” makes rumination worse.

Both can occur in the same person, and many people flip between them. Noticing which mode you are in on a given day changes what to do about it.

Signs you are overthinking

You may recognise several of these:

• You rehearse conversations in advance, often multiple times.
• Decision-making takes disproportionate energy, even for small decisions.
• You replay recent interactions, looking for what you should have said.
• You imagine detailed worst-case scenarios about situations that have not happened.
• You keep searching for one more piece of information before committing.
• You feel tired by evening without having done anything particularly demanding.

If this list is familiar, overthinking is probably the frame. The underlying driver is often anxious uncertainty rather than low mood.

Signs you are ruminating

Rumination tends to show up differently:

• You get stuck on specific moments from your past, playing them repeatedly.
• Your inner commentary focuses on what is wrong with you, not what you should do.
• You cannot stop asking why something happened, long after the event.
• Introspection feels compulsive, not clarifying.
• The more you think, the lower you feel.
• You confuse rumination with self-awareness or doing the work.

Rumination often masquerades as thoughtfulness. In practice it is anxiety-amplifying rather than clarifying. If you have been ruminating for weeks and feel worse rather than better, that is a strong signal that this is rumination rather than useful reflection.

Why “just stop thinking about it” does not work

With both overthinking and rumination, trying to suppress the thought tends to amplify it. Thought-suppression research (Mind, 2024) consistently shows that pushing a thought away tends to make it return more insistently. The useful move is not to stop the thought but to change your relationship with it.

With overthinking, that usually means tolerating uncertainty rather than trying to think your way out of it. With rumination, it means breaking the loop with activity, distraction, or compassionate re-framing, rather than deeper introspection. One of the counter-intuitive truths of rumination is that doing something, almost anything that is not more thinking, is usually more helpful than another hour trying to understand it.

What helps with overthinking

Practical steps that make a difference:

• Time-box the decision. Give yourself an honest half hour, make the call, and commit.
• Lower the stakes in your framing. Most decisions can be adjusted later.
• Externalise the loop. Say it out loud, write it down, or voice-note it. Loops die faster in daylight.
• Interrupt with movement, especially outdoors.
• Reduce the inputs. News, social media and group chats fuel overthinking.
• Counselling for the underlying anxiety, if the pattern is long-running.

What helps with rumination

Rumination responds better to a different toolkit:

• Behavioural activation. Small, defined activities, even ones you do not feel like doing, interrupt the loop. NICE (2022) recommends behavioural activation as a first-line intervention for mild to moderate depression precisely because it breaks ruminative patterns.
• Noticing when introspection has become compulsive, and stopping, even mid-thought.
• Compassionate self-talk. Rumination feeds on self-criticism. A kinder tone starves it.
• Counselling that focuses on the shame or sadness underneath, rather than more “insight”.
• Physical activity, which is one of the most reliable natural interrupters of rumination.
• Specific therapy models designed for rumination, including rumination-focused CBT, where appropriate.

Counselling for overthinking and rumination

Counselling is useful for both, but the sessions do different work. For overthinking, we look at the anxious core, the beliefs about getting it right, and the practical patterns that keep the loop running. For rumination, we look at the self-critical commentary, the shame or sadness it protects you from feeling, and the behaviours that are small enough to actually do.

At Thrive, counselling takes place in Central Milton Keynes or online across the UK, including Bedford and Northampton. BACP-registered counsellors work within a clear ethical framework (BACP, 2024). Fees are set out on the fees page, and the contact page is the easiest first step. There is also a related piece on whether what you are experiencing is OCD or overthinking, which is a useful next read if the loops feel more compulsive than reflective.

Being a thoughtful person without drowning in your own head

The goal is not to think less. Many of the most thoughtful people I see are also chronic overthinkers or ruminators, and their intelligence is a real asset. The goal is to use the thinking you have for the right problems, and to stop using it for problems that cannot be solved by more thinking. That shift takes practice. Counselling helps you build it.

Frequently asked questions

Is overthinking a sign of intelligence?

Not reliably. Overthinking is a sign of anxious uncertainty rather than intelligence. Thoughtful people often overthink because they can see more angles, which does not help them close the loop any faster.

Is rumination the same as reflection?

No. Reflection has a direction and tends to produce clarity. Rumination circles without resolution and tends to leave you feeling worse. If your introspection consistently makes you feel worse, it has probably become rumination.

Can I stop overthinking without counselling?

Many people reduce overthinking significantly with practical strategies, movement, better sleep and limiting inputs. If the pattern has been running for years or is affecting your relationships and work, counselling can shift it faster than self-help alone.

How is rumination linked to depression?

Rumination is one of the strongest psychological predictors of persistent and recurrent depression. Addressing the ruminative style, rather than just the content of the thoughts, is often central to lasting recovery.

Will journalling help or make it worse?

It depends how you use it. Expressive, time-limited journalling that moves you toward action can help both overthinking and rumination. Open-ended “why do I feel this” journalling often deepens rumination without resolving anything. If journalling leaves you more wound up than you started, change the format.
