I think my my friend is obsessed with me. PLEASE HELP!?

If you told her your password, it isn't hacking, and it is actually your fault for telling her. However, I am completely on your side for the rest. I would just tell her to leave me alone because she obviously is not a friend. She sounds like the kind of person that needs for attention all the time. Just ignore her. And if she REALLY starts going too far, contact me and I'll see what I can do about HER Facebook. Let's just say I'm good with computers...
