She is full of shit.... and she's trying to psych you out.
She's trying to put the scare in you.
If she was going to put all those things on you she would never tell you.
She obviously doesn't like you and is a mean-spirited person... so ignore her. Mind your own business, go your own way, avoid contact whenever possible, and be respectable and respectful if you have to have contact.
She's probably not playing with a full deck... and she probably knows that you don't have a full deck either... her for saying such stupid things and you for believing it.
Go make some nice friends... and if you're feeling uncomfortable buy one of the Confusion Charm and carry it with you. It causes confusion in people who are trying to send ill will in your direction.
I will put a link to the page where you can find it...
