Bad habits

Instead of going classes, i choose to go to the gym.. my god.. think i should stop this habit.. i dont really care what's what anymore.. tomorrow's a test for pathology and medicine and i still didn't revise.. not worried about it somehow.. sei mou.. parents still want me to study phd.. doubting whether i can face the books for another 4 plus years now.. tengok also want to vomit.. should stop these kind of thinking.. but still.. where should i go for easter? turkey or portugal?
