Catching and Checking Your Thoughts

A core CBT skill you can practise yourself: noticing the automatic negative thoughts that fuel anxiety and low mood, and gently questioning them, so they hold less power over how you feel.

What it is

This is one of the central skills of CBT, simplified for everyday self-help. It rests on a powerful idea: much of the time, it is not events themselves that determine how we feel, but our interpretation of them. The same setback can be read as "this is a disaster and it is all my fault" or as "this is hard, and I can handle it", and those interpretations produce very different feelings. In anxiety and low mood, the mind tends to generate automatic negative thoughts that are harsh, catastrophic or unfair, and we often believe them without question. This skill is about catching those thoughts and gently checking whether they are accurate and helpful.

Why it helps

Learning to notice and question automatic thoughts is at the heart of why CBT works, and it has strong evidence. The aim is not forced positive thinking, which rarely convinces anyone, but balanced, realistic thinking: seeing a situation more accurately rather than through the distorting lens that anxiety and depression create. Over time, this loosens the grip of the harsh inner voice and changes how situations feel.

How to do it

When you notice your mood drop or anxiety rise, pause and work through a few gentle questions, in your head or on paper. Many people find writing it down helps, especially at first.

Notice the situation: what was happening when your mood shifted. Catch the thought: what went through your mind, the automatic thought or image. Notice the feeling and how strongly you believe the thought. Then check it gently: what is the evidence for and against this thought; is there another way of seeing this; what would I say to a friend who had this thought; is this thought helpful, or just painful. Finally, come up with a more balanced thought that takes the evidence into account, and notice whether the feeling shifts even a little.

The aim is not to dismiss real problems but to think about them more fairly and usefully. Like any skill, it feels effortful at first and becomes more natural with practice.

When it is not enough

This skill helps many people, but when distress is severe, working through it with a trained therapist makes a real difference, and some difficulties need more than self-help. If anxiety or low mood is affecting your life, our condition guides explain the fuller treatment options. Use this skill alongside support, not as a substitute when more is needed.

When to seek help

If harsh, anxious or hopeless thinking is affecting your daily life, a professional can help you build these skills properly, usually through CBT. If you are having thoughts of harming yourself, please reach out today; our Get Support page lists services.
