She ran away because she wanted to be famous? Really, really NOT helping the sympathy here.
One in five girls are sexually abused in the United States. I really don't think you're that special or different. Take a look at the girls in the hallway and statistically a number of them have been through what you've been through. Fuck, I've been through it and I know it doesn't make me an outcast or outsider.
Seriously, Anna's got this attitude problem that makes it difficult to like her.
You're not special because you lost your virginity at age 13 - jesus christ, so did my husband and half of all sexually active female teens lose it at age 13-14. And bringing an untrained abused rottweiller into your bedroom is a very stupid thing to do.
