What metaphors are used in Necessary Losses by Judith Viorst?

In Chapter Ten, the author notes that adolescence "involves our nutty-desperate-ecstatic rash psychological efforts to come to terms with new bodies and outrageous urges" and can be frightening. Asserting ourselves against our parents at this age can make us feel guilty and angry. Viorst likens it metaphorically to "killing our parents" when we abandon our roles as children and take more control of our lives. Adolescence requires us to revise our personality and self-image, and any slight difference we perceive in our physical bodies causes us to feel inferior. Obsessions with body image, mood swings and "disharmony" are all part of this stage of life. Anna Freud noted the "inconsistent and unpredictable" behavior of
adolescents that causes fluctuations that would not be acceptable in other stages of life.
