Read this sentence from Sunday, January 2, 1944, in Anne Frank: The Diary of a Young Girl. I suffer now—and suffered then—from moods which kept my head under water (so to speak) and only allowed me to see the things subjectively without enabling me to consider quietly the words of the other side, and to answer them as the words of one whom I, with my hotheaded temperament, had offended or made unhappy. How does the phrase "head under water" affect the meaning of the sentence?
