What each step leaves you with
Taken from the recap at the end of each lesson.
After Lesson 1
- Anxiety is generally a response to a possible, uncertain or future threat; fear is a faster response to a present one.
- It shows up in thoughts, emotions, body sensations and actions.
- Self-guided learning is a starting point, not a substitute for professional care.
After Lesson 2
- A situation is what happened; an interpretation is the meaning given to it.
- Interpretations often arrive so fast that they feel like facts.
- Rethinking a situation has modest, real effects in experiments; forced positive statements can backfire.
After Lesson 3
- Rigid demands are absolute “musts” and “shoulds” that often sit beneath anxious thoughts.
- Writing a demand as a belief turns it into something you can examine.
- A flexible preference keeps what you care about while leaving room for reality.

Lessons, not treatment
These lessons can explain concepts and give you language for your experience. They can’t assess your situation. If anxiety is lasting for weeks, getting worse, or stopping you from working, studying, sleeping or seeing people, speak to a GP or mental health professional. In a crisis, contact emergency services, or call or text 988 in the US; Samaritans on 116 123 in the UK and Ireland.
