Dear Annie: I'm a 15-year-old girl who has been having problems with another girl for about a year. She's basically stalking me over the computer. I've received multiple threatening messages from her on MySpace. She says, "Why don't you just go and kill yourself already?" and that she is going to beat me up. Her latest tactic: She somehow got my cell phone number and calls me from a blocked number. I've changed my phone number twice. I've reported this to the police, but they won't do anything. This girl has a record and she's not afraid to go to jail. What can I do to get her to leave me alone? — Stalked in Inverness Dear Stalked: Apparently this is someone you know. Many states are now enacting laws against cyberbullying, and if this is a classmate, your school should step in. Since the girl has managed to get your cell phone number after it's been changed twice, it probably means you have a mutual friend who is giving it to her, so you might want to look into that. Talk to your parents, and let them speak to the police and the school principal. You can also contact the National Center for Victims of Crime (ncvc.org) at 1-800-FYI-CALL (1-800-394-2255).
