Keep a diary of your emotions and stress level for two days. For your diary, write entries in the morning when you first awaken, mid-morning (9-11am), lunchtime, mid-afternoon (2-4pm), and again before you go to sleep. Note your emotional state (including "content" if you feel no particular emotion) and stress level (low, medium, high).
Write a short explanation of what happened to create that emotion or stress level.
Explain how your emotions, stress level, and experiences are related. If you did not experience any stress at all, explain how you prevent or avoid stressors in your life.
