I agree that your d14 is probably going thru teenager stuff, but I think she probably needs someone else to talk with, like a C. Not sure when school starts for you all, but I talked with my kids c at school and gave her a heads up. She's going to do weekly check-ins with them, allowing them to talk if need be.
Maybe your d's c could approach it from new school/area for her and then be open with her for anything she may be struggling with. They aren't therapists, but it will allow your d a third party to confide in. Plus you can get around the W with her not wanting d to get IC, because a school counselor is there for her with anything she may need. ( I'm getting on my pedestal, this is what I'm going to school for ) Regardless, just like you, d needs someone to help her through this and her friends may not really give her the best advice.
