the worst in my life

oh god,
i did the worst things in my life,
just now went to sfm resit,
i got all the tips,
n yet,
i forgot everything in the exam room,
i really very upset with me,
i cried in front of yc immediately after the exam,
oh god,
i need a last chance,
i need to do my best !!!
i have to apologize to many people who put so many hope on me,
really sorry,
instead i should study well, prepare well before exam,
i know my mistake > <
sorry is the hardest words.
