Epilogue: Maya sits in an interrogation room. She looks calm, polished—the "good girl" again. She tells the police she has no idea where Elena is. She claims she was home all night. The detective leaves, frustrated. Maya asks for a notepad to write down her statement. She clicks the pen. Her inner monologue is silent. She doesn't need the diary anymore. She is the diary now. Bad Thinking Diary

  1. All-or-Nothing Thinking: Seeing things in black and white. ("If I don't get an A, I am a total failure.")
  2. Overgeneralization: Seeing a single negative event as a never-ending pattern. ("I forgot my keys. I ruin everything I touch.")
  3. Mental Filter: Dwelling on one negative detail while ignoring all positives. ("Ten people liked my post, but the one typo proves I am incompetent.")
  4. Discounting the Positive: Rejecting positive experiences by insisting they don't count. ("They only complimented me because they pitied me.")
  5. Jumping to Conclusions: Mind-reading (assuming you know what others think) or Fortune-telling (predicting the future will be bad).
  6. Magnification (Catastrophizing): Exaggerating the importance of problems. ("I have a headache. This is probably a brain tumor.")
  7. Emotional Reasoning: Assuming your negative feelings reflect reality. ("I feel stupid, so I must be stupid.")
  8. "Should" Statements: Criticizing yourself or others with "should," "must," or "ought to." ("I should never make mistakes.")
  9. Labeling: Attaching a global negative label instead of describing the behavior. ("I made a mistake" becomes "I am a loser.")
  10. Personalization: Blaming yourself for events outside your control. ("My friend is sad; it must be my fault.")
