I thought that Hannah must have told my classmates about my grade after promising not to. 3.Everyone must have been laughing behind my back!

I was so angry that 4.I went straight to Hannah and told her we weren't going to be friends any more because 5.她没能信守承诺. She was really upset and swore that she hadn't told anyone, but I know that the only people who see marks are the teacher and the student. She said that someone must have spying on us in the washroom, but I don't believe her explanation. I don't think I can ever truly forgive her. Now I’ve lost my best friend. What shall I do?
