Problem In school. im so stressed out?

ok basically our teacher wants us to bring our files and books home for revision for the upcoming exams. i brought my files home and today during recess i left it in the cupboard. after school i forgot to take those files. later my friend told me that they had a "raid" . All books and files under the table and in the cupboard were confisicated. it is not that worrying if my teacher confisicates my other stuff but she is my English and form teacher. If i do not bring my file tomorrow, im sure ill be severely embares and a bad impression from my teacher. im quite a good student in school but i really do not want her to leave a very bad impression on me and i also do not wish my clmates looking at me as im sort of their modal student and its preety embaring. im really stressed OUT!!!!! plz help me maybe through suggestions and so on. fyi this is my first offence so do help me!!!
