What is a CBT Thought Diary?
Cognitive Behavioral Therapy (or CBT for short) is a popular way to understand how our minds work. A CBT thought diary is just a simple, structured journal. It helps you notice, test, and change negative thoughts that pop up automatically when you are stressed.
The Basic Idea
How we feel is not just about what happens to us. It is mostly about what we tell ourselves about those events. If we can change our unhelpful thoughts, we can change how we feel and act.
A Simple 6-Step Guide to Clearing Your Mind
When your head feels messy, write down these six things to get a clearer view:
- The Situation: What happened? Who were you with? What triggered the stress?
- The Thoughts: What exactly was running through your head?
- The Feelings: What emotions did you feel (like anxious, angry, or sad), and how strong were they?
- Thinking Traps: Is your brain playing tricks? Are you assuming the worst, or thinking in "black-or-white"?
- A Friendly View: If a close friend had this exact problem, what kind and honest advice would you give them?
- The Result: Look at your original thought again. Do you feel even slightly lighter now?
