The girl, referred to by CNN only as Crystal, is one of many teens who use the Internet to seek comfort after saying they were sexually assaulted.

"Hi, my name is Crystal. ... I need some help. I didn't want to do it this way, but it's the only way I know that's going to work, that someone out there in the world is gonna listen to me," she says in the video.

Some rape victim advocates have said turning to the Internet for help may be a harmful choice because it exposes too much personal information including names, pictures and hometowns, CNN said.

"A rape survivor's intention may be to reach out, and we encourage that, but this is a dangerous way to do it," said Scott Berkowitz, president of the Rape, Abuse and Incest National Network.
