Confusion - the stepping stone to clarity (I hope..)

Everything I learn seems confusing. I don't understand what they mean, how they come about. I feel like the sun's covered totally by dark clouds. Only little rays of light shines through. Clarity's blocked by confusion. It's tough. The exam's in two weeks. Chemistry, Accounting, History... They're the ones that I can't give up on, I want to try till I get it. Chemistry is by far the worst. Don't understand anything and can only stare and stare at my book while others are rushing about with their answers. Everything seems to be in standstill mode at times. Barely get to be on the computer, play my piano and practically sleep. Was really glad I got the oral test out of my way today, I knew I'd regret it the whole weekend if I hadn't volunteered. Going to take tonight off homework and just relax and play games. No study stuff gonna bother me, at least not tonight...
