you did the right thing. Hopefully, her parents will get her some help. Just be there for her, be supportive. Maybe look online for information, so you can get an idea or ideas of ways to help as a friend. It's good that you two got involved and told someone. She may be mad at you guys for a bit, but I'm sure that will pass...just be ready for it. I hope things work out for her, and for the three of you as friends.
