Try your best, but dont put too much pressure on your self. You know, you can try get extra marks, for saying you were under ALOT of stress because of this bitch and your faggot teacher. This one kid in my school last year, got fucking extra marks because he said he was under alot of pressure because his do died roflz. You have a strong case, make sure you still got those messages she said about you, and you are sweeeeeeet, and you dont need your parents for help, you can take care of it yourself.
