Why I can't focus on my studies recently? No mood at all. I intend to do revision for preparing the coming final exam but don't know why I can't do it. Want to do it but no mood to do it. -.-   Who can help me? No motivation to do it. I really want to study if not the result come out will be very worse. Furthermore, I don't want to resit! So God, please grant me the power to study! Please...I beg YOU... Okay? :'(
