Describe the structure used to organize helen's story

The structure is in three parts. The first two, Miss Keller's story and the extracts from her letters, form a complete account of her life as far as she can give it. Her style is called Affectionate Recollection. Despite the hardships Keller overcame, there is no sadness, self-pity, or bitterness in The Story of My Life. She willingly tells of her childhood fits and how angry she was at the time, but she relates these episodes with calm recollection. Her focus is on the people she loved and the wonderful experiences she had in the first twenty-two years of her life. She wistfully recalls moments spent in the orchard or up a tree. Remembering her summer at Cape Cod, she writes, "As I recall that visit North I am filled with wonder at the richness and variety of the experiences that cluster about it." She describes the beautiful scent of the outdoors and the tempting smells coming from the kitchen on Christmas. At the very beginning of the book, she comments, "When I try to classify my earliest impressions, I find that fact and fancy look alike across the years that link the past with the present. The woman paints the child's experiences in her own fantasy."
