really angry and in trouble

It has been a long time that I never feel so angry like today. Besides feeling angry, I know that I meet a big trouble.
Let me show you the thing make me angry first. In today afternoon, after my lab, I walked towards the Computing Applications Building, while feeling happy about I got a really high score of my mid-term and enjoying the really sunshine. At that time, I never think that one person who would make me extremely angry was waiting for me in the LAS Student Affair office of the Building. In fact, I waited for her for a while, before I met her.
Why did I go to the office? Because, I wanted to ask the answer about evaluation about my syllabus that I handed in at the beginning of this semester. She told me that after eight weeks I would get the answer; however, I got little information from her nowadays. I tried to use e-mail to contact with her before, and got no answer. When I entered the office, everyone was working in it except her. No one knew where she was, so the only thing I can do was wait. Finally, she came, “what can I do for you?” asking with her inhospitable voice. After I told her me question, she checked then told me there was nothing in my folder. How weird it is? I was definitely sure that I gave my syllabus to her, and also remembered that while I was waiting for her explain, she asked me with her fierce voice “do you have other things?” “So I have to hand in it again?” “Absolutely.” Her answer drove me really angry. It is not my wrong to lose the syllabus, it is her wrong! And because of her incautious I have to wait for another eight weeks, which means it should be really hard for me to select me course for the summer school and for the fall term. I waited for her apologize, but got nothing. Then I walked out this building with angry.
As I just transferred here from China this semester, how many credit I can get is the main problem that make worry about every day. Before transfer, I was a sophomore in China. Nevertheless, they decided that I can only transfer 15 credit to UIUC, and only 5 of them was really transfer. Even though I take 18 credits this semester, I will still freshman standing until next spring, when I should be a junior. As a result, I can’t choose Sherman which is a dormitory for students except freshman to live for next year, and have to study pretty hard to catch up with others. I am not mean to complain my transfer, but I really don’t know why the credit is how hard to get!
After I went out the Computing Applications Building, I thought about many times to come back and argue with this person. However, I gave up. Because I tried to consider that maybe she was in her trouble, such as lower salary for economic crisis or illness for family member. I just hope that she can understand the difficulty of transfer students.
