Irish actress Evanna Lynch appeared on The Late Late Show on Friday night.

Lynch wrote a letter to J.K Rowling when she was 11 years old thanking her for a creating a world (Harry Potter) in which she can escape to.

She described her eating disorder as a “retreat from life”, and said that it took all of her energy, resulting in her losing all of her friends.

Lynch said, “That’s what I wrote to J.K Rowling, I said: ‘You don’t understand what a big deal it is to me that there’s one thing in the world that can take my mind off this obsession and this illness – and that’s Harry Potter.”
