The strange tale of Amanda Knox was thrown another twist last month when an Italian court over turned Knox’ 2011 acquittal. Knox, who was a foreign exchange student in Italy, was convicted in 2009 of the murder of her roommate, Meredith Kercher. The court case has brought international scrutiny of the Italian justice system.

Despite the latest court ruling, Knox is now back in the U.S. and is moving on with her life. She has penned a memoir that will be published on April 30.

As part of her media tour to promote the book, Knox spoke with People magazine this week, telling the publication that she is still affected by the murder, her conviction, and the four years she spent in an Italian prison.

When Meredith was murdered and I was arrested, it was so shocking,” Knox told People. It was paralyzing. Everything toppled.”

Knox related that, while in prison, she contemplated suicide. She now lives in Seattle and attends the University of Washington.

“Things creep up on me and all of a sudden I’m overwhelmed by the feeling of helplessness and that desperation and fear to even hope,” she told People. “Just that can make my heart race and makes me paralyzed until I can breathe it away.”
