(Sept. 16) An unnamed diarist, whom the novel's title refers to as Alice, records her first entry in a diary (these entries constitute the entirety of Go Ask Alice). She explains that she bought the diary yesterday when, in high spirits after being asked out by a boy she liked (Roger), she believed she finally had beautiful thoughts to share with herself through writing. Today, however, Roger has apparently rejected her. Alice fears a humiliating day at school tomorrow. (Sept. 17) The next day at school, Alice is miserably insecure and wonders why people always seem to hurt her feelings.
(Sept. 19–23) Alice's fifteenth birthday passes, and her boredom with life is interrupted only by weight gain and her accompanying self-loathing. But she learns that her father, a college professor, has accepted a teaching position at a different college and the family will move at the start of the new year. This perks Alice up, and she asks her diary to help her stay diligent in her mission to remake herself by losing weight. She fantasizes about Roger's asking her out and her rejection of him.
(Oct. 10) The family excitedly unites in preparation for the move. Alice is especially eager to start her life over, although she wants to take along her books, her most treasured possessions. (Oct. 17) Now that she knows she'll soon leave, school is fun again, and she doesn't care about Roger anymore. (Oct. 22) Alice goes on a date with a boy from school and obsesses on gaining weight and eating to her diary. She concedes that she doesn't like this new boy as much as Roger, whom she believes is the love of her life. She can't picture losing her virginity to anyone but Roger, and even then she can't imagine herself having sex or having a baby.

Alice remains insecure and wishes she were more successful in every way.

Go Ask Alice opens with issues that are as relevant to teenagers today as they were in the 1960s. Alice is a perceptive, sensitive, and insecure girl who worries about boys, peer acceptance, her blossoming sexuality, and her family. She displays a heightened intelligence and an awareness of her emotions and records her sophisticated observations and feelings with lucid, readable prose. Alice's saving grace, here and throughout the novel, is her ability to explore herself through her diary while the outside world often disappoints. She capitalizes the word "Diary" and refers to it as a person, confiding in it and asking it to monitor her weight-loss regimen as if it were a close friend. Indeed, this is one of the major themes of Go Ask Alice; through her diary, she comes to know herself well and feels "Diary" knows her intimately, too, when no one else seems to. Her books fulfill a similar function; they harbor Alice from the drabness and pain of the real world and usher her into an imaginative world that becomes part of her own. The confusion in her memory over what she has read and how she has lived shows that Alice loves writing because it lets her experience a world that at the same time experiences her.
