Racist Lecturer

clearly, aussie ppl dont have much experience mixing around with many races,particularly chinese. i've got this lecturer teaching me Academic Culture(duno why need 2 study tis stupid subj and its so fucking hard) and the kind of attitude she uses to treat my class is 'omg why r u so stupid' kind of attitude. the reason why i say she is racist is becoz last 2 wks ago, 1 of the boy in my class was playing with his hp and she said 'turn it off or i'll send u out of the class,if u wana continue to play with ur hp during class why dont u go back to China and continue doing what u're doing and don't come back here' ........that is the exact words she used on the boy.... i somehow think she has something against the chinese. funny is that, today (27.08.09) i was suppose to hand in my report that is due today itself. so the lecturer said we should go up to the front 1 by 1 to let her check through so that if there's anything wrong,we still can go and mend it and reprint to hand in. so i went...when she opened my report she said 'when did u finish this? yesterday?' then i said 'no,i finished it last week' and she said 'wow that is a surprise' and of coz i was thinking what the fuck who do u think u are simply assume that i finished it last minute. FYI i had a week sem break and that is the time i used to do my asmnts,in fact, i had so many asmnts to rush so of course i must finished the 1 that i think it is easy so that i can leave the others to crack my brain next and she can just SAY that i finished it yesterday...i duno how to say it in english but in cantonese is i have already 'bei yan yun wong'........really is what the fuck. i prayed and prayed every night that hopefully i can just hand in my assignments without any complains or watever....obviously this week,nothing has been going my way and obviously my prayers aren't being answered. i feeled so fucked up right now.i'm so frustrated,depressed and sad. in fact i feel like crying and i think i might have an emotional breakdown soon.
