How can I interrupt repetitive negative thought patterns?

You can interrupt repetitive negative thought patterns by changing what your mind is doing next rather than trying to debate the thoughts themselves.

• Shift attention to an external activity: If the thoughts are repetitive but not deeply disturbing, anchor your attention to something outside the loop by getting into action or another activity that draws focus away from the thought 1.
• Use mindfulness to train focus: Even 5–10 minutes of breath-focused meditation can improve your ability to hold attention on one thing, which helps move attention off repetitive thoughts 2.
• Write disturbing thoughts out in detail: If the thoughts are intrusive and upsetting, journaling them in complete sentences with as much structure and detail as possible can reduce their emotional load and frequency over time 3.
• Get close to the specific narrative: The goal is to make the disturbing thought into a more familiar, less emotionally charged story; that often works better than trying to suppress it 4.
• Change the frame to something helpful: Ask whether the thought is helpful in your ongoing life, not whether it is perfectly true, and choose a story that quells the loop and brings you back to the present 5.

In short: redirect attention for simple loops, and for upsetting loops, bring the thought into words and structure until it loses power.
