I Need to Vent

I'm tired of this girl from high school stalking me on Facebook. Yesterday I saw that she made a new account and I blocked it. This is the 4th account I've blocked. I even had to change my name and picture because I've become so paranoid. I cut contact from her a year ago because I was going through my personal issues and our unhealthy friendship wasn't helping. She's very obsessive and it was too much. She hasn't messaged me but I know she has a history of cyber stalking. My mom saw her last month and asked if I was home from the uni yet. Some people just can't take a hint.
