Do you remember if you went through this at her age? How similar is her personality to yours, generally?

Don't feel bad about the DVD player. When I was a teenager I'd spend hours alone in my room with _nothing_. I'd sleep or stare at the ceiling. Maybe she just needs a lot of uninterrupted time to process all the normal changes in her life right now. Maybe every teenager on earth goes through them, but it's still the first time for her, and it's strange and kind of scary.

((((Sally)))) She's going to be fine, because _you_ are her mom.
