Siljie, your "friend's" behavior is totally unacceptable. Do not delay, inform
- your parents
- your teacher(s)
- your counselor(s)
Make a formal complaint or report now. If you get no response from any of the above, do not hesitate to contact the police. Gus1234U speaks wisdom; don't let this escalate.
