In an interview with the UK version of Glamour magazine, Amanda Seyfried confessed that she has been having panic attacks because of ... interviews. Hopefully she wasn't breathing into a sack and crouching under a desk as she gave the interview:
She feels anxious ahead of premieres and live interviews and she’s sought professional help to combat her issues.
"That's been such a great tool, and my therapist told me that I passed with flying colors, but we'll see how things go."
I had the same problem in college. My therapist was a bucketload of Xanax. I passed seeing flying colors, too.
