terrible, disaster, hardship

As you know, I went to New Zealand from 22th Jan to 21th Feb. All of us who went there have to write a report about what they studied. I have to hand in by 12th Feb. This is the first day of the first semester. So, my spring vacation has remained for only one week! However I haven't completed my report yet, and I forget English. It is very hard for me to write the more than 700 words English report. A good idea doesn't come in my mind. I want to give up the report and go anywhere. If I will do such things, I cannot get a credit and I must pay 120,000 yen because this 120,000 is support from the university. I have NO money now. I don't want to pay extra money anymore. Help me!!
