Understanding the Cycle of Overthinking—and How Therapy Can Help
Most of us have found ourselves lying awake at night, replaying the same thought over and over. Maybe it’s something we said in a meeting, a decision we’re unsure about, or a vague sense that something bad is going to happen. These repetitive thought patterns—known as thought loops—can be exhausting and difficult to break. For many people, especially those experiencing anxiety, stress, or perfectionism, thought loops can dominate the mind and impact day-to-day life.
At Cova Psychology, our psychologists in Melbourne often support clients who feel stuck in their thoughts. If this sounds familiar, you’re not alone—and you don’t have to stay trapped in this cycle. In this post, we’ll explore what thought loops are, why they happen, and how Cognitive Behavioural Therapy (CBT) can help you move forward.
What is a Thought Loop?
A thought loop is a repetitive cycle of thinking where your mind keeps returning to the same idea, question, or worry without finding resolution. Often, the thoughts are intrusive, negative, or circular—meaning they go nowhere but still feel urgent or important.
Common themes in thought loops might include:
Doubting a past decision (“Did I say the wrong thing?”)
Fearing a future outcome (“What if I lose my job?”)
Replaying a conversation or mistake
Trying to mentally ‘solve’ a feeling without much success
These thoughts may feel compelling, like they must be resolved before you can relax. But instead of leading to clarity, they usually increase mental fatigue and stress.
Why Do Thought Loops Happen?
Thought loops can develop for a few different reasons. For some people, they are linked to anxious thinking styles—especially when the brain is trying to predict or control uncertainty. Others may find they spiral into loops when they’re feeling overwhelmed, guilty, or unsure of what to do next.
From a psychological perspective, thought loops are often driven by:
Cognitive distortions (unhelpful thinking patterns such as catastrophising or black-and-white thinking)
Avoidance of difficult emotions (trying to think your way out of feelings)
Perfectionism (feeling unable to let go of a decision until it’s ‘perfect’)
Intolerance of uncertainty (a need to have all the answers now)
In some cases, thought loops can also occur alongside conditions such as Generalised Anxiety Disorder, OCD, or depression. That doesn’t mean you have a diagnosis—it just means your brain may be falling into unhelpful patterns that are common in these presentations.

The Role of CBT in Treating Thought Loops
Cognitive Behavioural Therapy (CBT) is a widely used, evidence-based approach that can help people understand and change unhelpful thinking patterns. One of the strengths of CBT is that it doesn’t just explore why you think a certain way—it also gives you practical tools to respond differently.
In therapy, a psychologist will help you identify the specific thoughts that are looping, examine the assumptions behind them, and develop new ways of relating to those thoughts. You’ll also work on behaviour—because how we act often fuels how we think.
Some of the key strategies used in CBT include:
1. Thought Monitoring
The first step in changing thought loops is learning to recgonise them. Your psychologist might encourage you to keep a thought diary—briefly noting when the loop begins, what it focuses on, and what emotion it triggers. Over time, this helps you spot patterns and triggers that might otherwise go unnoticed.
You may discover, for instance, that you start looping when you’re tired, after seeing a particular person, or before important events. Gaining this insight can be a game changer. For more on how insight builds emotional awareness and resilience, you might find our article on building your insight useful.
2. Identifying Cognitive Distortions
CBT teaches that we all have ‘thinking traps’—ways our mind distorts reality. When you’re stuck in a thought loop, it’s often because one of these distortions is driving the show. Some common ones include:
Catastrophising: assuming the worst will happen
Mind reading: believing you know what others are thinking
Should statements: holding yourself to rigid rules (“I should never make mistakes”)
All-or-nothing thinking: seeing things in black and white terms
Once you’ve named these patterns, you can begin to challenge them and develop more balanced, realistic thoughts. Our CBT services in Melbourne offer personalised guidance in learning how to manage these thought patterns effectively.
3. Behavioural Experiments
Sometimes, the best way to interrupt a thought loop is to test it out. Let’s say you keep replaying a conversation, worrying that you sounded foolish. Your psychologist might guide you to check the facts (e.g., by asking a trusted friend for feedback) or try behaving differently next time and observing what happens.
These experiments aren’t about proving the loop wrong with logic alone—they’re about helping your brain experience something different, which can be far more powerful than reassurance.
4. Learning to Let Thoughts Be
One of the biggest traps of a thought loop is the belief that thinking more will eventually lead to resolution. CBT challenges this idea by introducing the concept of thought defusion—a technique borrowed from mindfulness-based approaches.
Instead of trying to ‘solve’ or eliminate the thought, you learn to notice it without attaching to it. Your psychologist might help you practise exercises such as:
Labelling the thought (“There’s the ‘what if’ again”)
Imagining the thought as a passing cloud
Practising present-moment awareness through your senses
This shift helps reduce the emotional grip the thought has on you—making it easier to move on. For many clients dealing with trauma-related thought loops, this approach is also integrated into PTSD treatment at our Melbourne clinic.
When Thought Loops Impact Daily Life
Thought loops don’t have to be constant to be distressing. Even occasional overthinking can interfere with work, relationships, sleep, and overall wellbeing. You might notice:
Trouble concentrating
Difficulty making decisions
Feelings of guilt or shame
Avoidance of situations that trigger rumination
Physical symptoms like fatigue, tension, or upset stomach
If you’re finding that your thoughts are interfering with your ability to enjoy life—or they’re making you feel stuck—it might be time to reach out. A psychologist can help you understand what’s happening and work with you on ways to feel more in control.

Thought Loops and Mental Health in Melbourne
Living in a busy city like Melbourne comes with its own set of challenges. Many of our clients at Cova Psychology juggle demanding jobs, social expectations, and long commutes, all while trying to maintain a sense of balance. Thought loops often show up when life feels too full—or too uncertain.
You don’t have to be in crisis to benefit from therapy. In fact, many people come to therapy simply because they want to stop feeling overwhelmed by their own minds. CBT offers practical strategies, but also space to explore the deeper beliefs that may be keeping you stuck.
For clients who prefer the flexibility of remote access, we also provide telehealth sessions with psychologists in Melbourne who are experienced in supporting clients through CBT, anxiety, trauma, and more.
You’re Not Alone—And You’re Not Broken
One of the most important things to remember is that having looping thoughts doesn’t mean something is wrong with you. It means your brain is doing what it thinks will help—but it’s become a bit overzealous. With support and practice, it is possible to build new habits of mind.
At Cova Psychology, we offer evidence-based therapy for individuals who feel caught in their thoughts. Our psychologists take a compassionate, collaborative approach—helping you feel heard, understood, and supported as you learn to respond differently.
You don’t need to figure it out on your own. Therapy is not about being told what to do—it’s about being guided back to your own clarity and confidence.
