Magic Forums

I have absolutely no clue why, but there is this one vampire girl named Elizabeth (idk her last name) who completely hates me. I was hanging out with two of my friends, both vampires, Nathan and Myrandah, and out of seemingly no where she came up and attacked me, saying something to Nathan and Myrandah about 'bringing a snack'. She was trained in magick, and when Nathan and Myrandah tried to help me they were thrown away. Elizabeth had tried to bite me, and got her fangs halfway in my neck, until Nathan got her away from me, luckily. That was about two years ago. Now I have a barely noticible scar from it, but whenever she's within a close enough distance from me (I have yet to figure out how long that goes) My neck will hurt like crazy. Nathan and Myrandah said that she's been getting nearer to my town, and I have no clue what to do, I'm not that good at magick. Can anyone tell me how I can protect myself if she comes near? Cause Nathan and Myrandah live in Seattle, which is states away from me :(
