As others mentioned I'd work with her more and if she shows no signs of calming you could look for a more appropriate home for her: my SSTP went through a super drama queen stage where she would lunge and THROW herself across the room at you and though she was on the smaller side she could be intimidating! But after working with her (and time) she's calmed into a wonderful 13+ lb adult and is more than I could have ever asked for. I'd see if your girl could turn out the same.
