Your mind never truly stops. You replay conversations from three years ago. You imagine worst-case scenarios that will probably never happen. You make a decision, then spend the next four hours questioning whether it was the right one. You are not broken. You are an overthinker. And this workbook was built for you. The Overthinking Brain is a 90-day CBT-based workbook that gives you a daily system to interrupt the spiral, examine your fears honestly, and build real evidence that your mind has been overestimating threats your entire life. Each day takes five minutes morning and evening. Over 90 days you will build something no advice can give you: proof that your feared thoughts almost never came true. Inside you will find: - Daily reality checks using core CBT techniques - Morning and evening pages that work as a complete system - 13 science-backed weekly insights on how the anxious brain works - A Personal Trigger Map to identify your patterns - A Calm Protocol built from your own 90-day experience - A Final Reflection to close the loop on your journey 90 days. One page at a time. The spiral ends here.
