I dont know what im doing

I got back 3 of my exam papers. Physics, Chem & Maths. E,E & S. Econs will be really bad I guess...and I really dun wan to fail my GP. I really dont know what im doing these few days. Time flies really fast. Im always playing my ruan or listening to music and slack. Although I did some of my tutorials (esp. chem) and read some notes, its not enough. I dont feel like going out nowadays, probably due to the results, but I really dunno what's the problem. People asking me why I look so emo-ish these days, I really dont know. I dont even know whats happening to me oh my gosh. Im also becoming abit anti-socialish these days...and rather easily irritated...im really sorry...
