According to CBS, Gisele‘s work caused her stress and anxiety, which resulted in her panic attacks.

“You know, I was in tunnels. I couldn’t breathe. And then I started being in studios, and I felt, like, suffocated,” she recalled.

Gisele continued, saying, “I lived on the 9th floor, and I had to go up the stairs because I was afraid I would be stuck on the elevator, and I’d be hyperventilating. … You know when you can’t breathe even when the windows are open, you feel like, I don’t want to live like this, you know what I mean?”

The model said that she thought about committing suicide by jumping “for, like, a second.”

Elsewhere in the interview, Gisele discussed her divorce from Tom Brady and how it felt to be moving on.
