So do you think your DD is depressed? I'm not sure of the back story here to really give any useful advice, but I am getting to know female pre teen hormones w/ my own DD.
She's attached to the computer, her peer group & has tunnel vision right now on life.

Is she just complaining about music in general?
I'm sorry but I'm not sure I understand it all & I saw no one replied to ur post so I wanted to ask for more info. Maybe that'll help people respond more.
Thanks
