Entering Exam Hell

Exams start this week and even though I'm so stressed about them in a way I don't really care anymore. I mean I can't seem to get myself to care enough to do anything (like study or revise my essays that are due soon). I know this sounds weird, but I'm feeling kind of burnt out lately. I'm just very tired recently and have major eye pain, with the blurry vision and headaches (too much computer time, I suppose). I don't know why I can't motivate myself to do the things I need to do. I feel like I'm on some kind of systems shut down, which although is possible is most unlikely. *sighs* I just want to go home and not have to worry about school anymore. Oh well, such is life and this is exam time.
