Intrusive Thoughts and Distress Tolerance

Understanding the Experience of Unwanted Thoughts

Most people experience intrusive thoughts from time to time. These are thoughts that seem to pop into your mind out of nowhere – often unwanted, disturbing, or out of character. You might suddenly picture something violent, inappropriate, or deeply upsetting, and wonder: Why did I think that? What does it mean about me? For some, these thoughts are fleeting. But for others, they can become a persistent source of distress.

At Cova Psychology, our psychologists in Melbourne often work with people who are struggling to manage intrusive thoughts. These experiences can feel frightening and confusing, especially when they go against your values or sense of self. With the right support, it’s possible to understand these thoughts differently, reduce their impact, and build a stronger sense of emotional resilience.

What Are Intrusive Thoughts?

Intrusive thoughts are involuntary. They often involve disturbing images, impulses, or ideas that feel unwanted and uncomfortable. Some common examples include:

• Imagining harming yourself or others, even though you don’t want to

• Sexual thoughts that feel inappropriate or distressing

• Thoughts that question your morals, identity, or safety

• Repetitive fears about illness, contamination, or danger

• Religious or blasphemous thoughts that go against your beliefs

These thoughts don’t mean you are dangerous, immoral, or mentally unwell. In fact, having these thoughts doesn’t mean you’ll act on them. They’re more common than most people realise – but because they feel so confronting, many people avoid talking about them altogether.

When intrusive thoughts stick around, people often respond with guilt, shame, or repeated mental checking. You might try to “un-think” the thought, replace it with something else, or seek reassurance that you’re not a bad person. Unfortunately, these efforts usually backfire and make the thoughts feel even more powerful.

When Intrusive Thoughts Become a Problem

Intrusive thoughts are part of the picture in several mental health conditions. They can be a feature of:

• Obsessive-compulsive disorder (OCD)

• Anxiety disorders

• Post-traumatic stress

• Depression

• Body-focused conditions such as body dysmorphic disorder or eating disorders

If you’re finding that intrusive thoughts are consuming large amounts of your time or energy, it might be helpful to explore whether something like OCD could be part of what you’re experiencing. These thoughts can also appear in the context of trauma – our psychologists often support people managing PTSD symptoms, and you can learn more about our PTSD treatment in Melbourne if that feels relevant to you.

But intrusive thoughts can also arise outside of a specific diagnosis. What tends to cause the most distress is not the thought itself, but how we relate to it. When a thought triggers fear or shame, we often try to control it – and that’s when it can become more frequent and intense.

The Role of Distress Tolerance

Distress tolerance is the ability to sit with uncomfortable emotions, sensations, or thoughts without needing to immediately escape or fix them. It doesn’t mean liking the distress or putting up with suffering forever – it means having the skills to ride the wave, stay grounded, and respond in a way that’s aligned with your values.

For people experiencing intrusive thoughts, distress tolerance is a key skill. The goal is not to get rid of the thought entirely – because thoughts, by nature, are unpredictable – but to change your response to it. Instead of panicking, avoiding, or reacting with shame, you can learn to notice the thought, name it for what it is, and let it pass without needing to act on it.

This takes practise and support, but it’s absolutely possible. In therapy, we can help you build the confidence to do this – one step at a time.

Strategies That Can Help

At Cova Psychology, our psychologists in Melbourne draw on a range of evidence-based strategies to help people manage intrusive thoughts and build distress tolerance. Some of these include:

• Mindfulness and defusion – noticing thoughts as mental events, rather than facts or threats

• Values-based action – focusing on what matters to you, even in the presence of distress

• Emotion regulation skills – calming your body and mind when anxiety spikes

• Cognitive restructuring – gently questioning unhelpful beliefs about thoughts

• Behavioural experiments – testing fears and seeing what actually happens

We often draw on therapies such as cognitive behavioural therapy (CBT), acceptance and commitment therapy (ACT), and dialectical behaviour therapy (DBT). These approaches can help you move from feeling trapped by your thoughts to living a life that feels more open, grounded, and fulfilling.

Therapy as a Safe Space

When intrusive thoughts feel taboo or frightening, it can be hard to open up about them – even with people you trust. That’s where therapy comes in. Speaking with a psychologist offers a private, non-judgemental space where your experience is taken seriously and treated with care.

At Cova Psychology, we understand that many people worry about what their thoughts say about them. We’re here to help you unpack those fears in a way that’s kind, collaborative, and focused on what matters to you. You don’t have to justify your thoughts, and you won’t be told what to think. Instead, we’ll work with you to understand your experience and find practical ways forward.
