The assignment was getting too much too handle. The problem was that it was summer vacation and a project to be done in that time, but since you played all the time and now trying to rush in everything at the last hour is not going to work for you. This has led to development of dark circles under your eyes. You for sure are very tired with the entire thing and you are just half way through. The best thing to do is to take timely breaks so that you always have a fresh mind to write.
