College.... a dream or a nightmare?

Im studying music in chile my natal country, but its SO SO SO DIFFICULT!!! i mean it! i am repeating the first year!!!!! cause my grades are not SO good i mean, not enough to pass and im really stressed out! > : ( its not fair!!!! i am generally a lazy guy but... I don´t know, its just like that and its really REALLY difficult for me to study alone, when i am in class I pay attention, in fact, i always sit on the front (becouse besides i have a bad eyesight ((what i hate completely, becouse I HATE using glasses)) but when its time to study or even start the test my mind goes white! and I dont get a thing or the things doesnt work out! its so frustrating! and i want to play better than what i can already play but its really difficult so the ASSHOLE WHO SAYS THAT, EVEN ART OR MUSIC (which is art too but whatever) ITS EASY, PLEASE, KICK HIS ASS VERY DEEPLY SO HE WILL REGRET! in my country we are not valued or really taken into account by the way, thats one of the reasons I hate my country, people doesn´t appreciates art and listen to RAEGGETON shit music instead of rock or jazz or even blues! i feel.... awful!
