Overthinking often involves two destructive thought patterns--ruminating and incessant worrying.
- Ruminating involves dwelling on the past. "I should have stayed at my last job. I would be happier than I am now.""My parents didn't teach me how to be confident. My insecurities have always held me back."
- Persistent worrying involves negative predictions about the future. "I'm going to embarrass myself tomorrow when I give that presentation. I know I'm going to forget everything I'm supposed to say."
