Stress During Exam Period!^^

Somehow I will feel extremely depressed and down just before every exam is tested. Well, I just feel as if I have not done enough is all the paper that I am going to deal with. But then, after the first 2 papers, I actually feel just ok and everything just seems like normal. Oh well, with 3 more papers to come, i just feel as if time is so running out. I have not much time left. I still have statistic, anatomy and physiology and Malay curriculum to be tested from Tuesday till Thursday! Just hope to do my best and lessen time spend on internet! Come on.^^
