Don't worry about what she says about your appearance.  If you do what she says today she might just threaten you about something else tomorrow.  Please report the threats to your teacher, counselor, and/or principal.  Maybe you can ask a parent or neighbor to pick you up right after school so you don't have to hang around that girl.  She's in the wrong, not you!\n\nAdditional: Jinx has the right idea.  Please get adult help on this one.
