She sounds like she has a lot in common with many of the girls where I work. All of them are there (at least initially) because someone (usually their parents) cares more about them than they do about themselves. The seventeen-year-olds can be particularly frustrating because if they don't decide that they want to change their lives by the time they turn 18, they can choose to leave, and then there is no more that we can do to help them.

Sometimes it takes being sent someplace other than home, so that they can get a perspective on what they had and didn't know it.
