i feel hurt

hello hell.
today i took my maths mock paper and i bloody hell screwed it upside down. it was quite ok but i didnt know why i couldnt do it. the last question i screwed it because i tot of using cosine rule but when i found the angle, i forgot to use it so i left blank and the rest of the question gone. i left alot of blanks too and had many careless mistakes. die la! its a fail. 20% of term 3 gone to the 3 test we took. *sobs sobs* i feel super depressed.
after CO played volleyball, monkey and captain's ball wif the cute soft ball i bought because i was depressed. managed to make me forget bout my worries for once. but after the game, i still felt sad. slowly went home thinking of how i disappointed mdm ng and how to buck up for MRs. i really got to do well to pull up my marks. LORD PLS HELP ME.
now i cant stop thinking of how to face mdm ng on monday. i am so sorry mdm ng...
