NO...no...No...nO

Assignment, test and etc. all come together. Wat la?! Test is just around the corner, but I still haven't study...many effort need to put to score. Material(study) literacy is the knowledge and understanding of material study and their uses. Haiz...I had made the same mistake again. While I study for one subject, my heart just flow to those task I haven't finish. Then, finally, I couldn't oso reach all of that. All become " half half". I know that shouldn't be the skill of study, but I really donoe how to avoid it. These had make me worried, become more annoyed, couldn't sleep tight. How should I do? Feel very hopeless~ I have tried to control my temper, but it seem not to be work. Perhaps I have to deal with the root cause of skill studying. Only the one who tied it can untie it! Gambateh~

p/s: Can I do that? I'm wondering to my ability..haiz:-(
