"I was a fan of the show, and I got the call to do it," she told MediaVillage. "Then when I did it, I had such bad anxiety because they kept changing the script. It's very hard to be a guest star because you're not a part of it, and you're really trying to figure it all out. They were trying to figure out what the character was, what the scene was, and it was changing, and changing, and changing. It all made me so anxious that I could barely do it."
Grey didn't realize it then but she was grappling with intense anxiety.
"I had a lot of performance anxiety," she continued, "and I just didn't understand at that time that I needed help in the anxiety department."
