Oh Liz, no wonder you're upset!
Can you talk to her parents? Can you talk to the friend? I know it's a fine line to dance, 'interfering' with other people's kids, but they probably don't know this is happening. And as for the friend--she may think she's growing up, but she's still very young and this needs to be nipped in the bud NOW. By all means, talk to your OWN daughter about this--she most likely knows about her friend already, but she's young and she'll need some guidance on how to handle it.
Nancy suggested something fishy, and that's a great website. Consider going to your local library and seeing what you can find there, too (those books are...approximately 618, if I remember right from working there...

) Possibly see if there's something available in your community, too.
I'm sorry you're in this bad place.
