Can this freak really track my yahoo account?

Track you just by your email address? I think you're safe. She doesn't know what you look like, where you are. If she went to the police they wouldn't tell her where you lived if they knew. She would need some proof of a crime before the police would act or even consider looking into it. She is just narked because she wanted a kitten. Head up and don't give this a second thought. Let it go.
