Dear Mary, I am not happy these days. I am new in this class, you know, but I don' t have any friends here. I always have to keep quiet and put my heart into my study. I thought things would be fine. It's very hard for me to be happy and sometimes I get lost in thought. So I can't follow the teacher. I know it is not right like this, but I can't control myself in class. Then my study is bad now. Some students make fun of me. I feel hurt , but I don't show my anger. In fact, I have to hide  my unhappiness. I feel terrible. Dear Mary, I really don't know what to do now, Can you help me? Yours, Jane ,A, B, C, D,, . Who wrote the letter?
