How did Helen Keller get out of the traumatic experience of ‘Frost King’?

Helen Keller had written a story called The Frost King and sent it to Mr. Anagnos of the Perkins Institution for the blind for his birthday. He is delighted and impressed by her work and published it in The Perkins' Institute report. It was then discovered that Helen's story had resemblance to “The Frost Fairies” which was published in Miss Margaret T. Canbey's book “Birdie and His Friends”. Helen vows that she had no memory of hearing the story and Annie Sullivan also claimed that she had never heard of “Birdie and His Friends”. But the Committee had decided that Helen had plagiarized from “The Frost Fairies” and this left her traumatized and she refused to resume writing. Her relationship with Mr. Anagnos had also been severed. She began to double-check her letters to her mother to ensure all the words were her own and recived consolation from Miss Sullivan and Miss Canbey. Anne escaped from this trauma by understanding that it a lesson to be learnt from life.
