My ex and now friend has multiple issues that I'm not sure how to help with

My ex is going through a difficult time and is struggling with self-harm and emotional distress. I say difficult time but this stuff has been going on for awhile it just recently got worse after our breakup. I'm very concerned about her well-being, and she's not open to seeking help herself. Can someone provide guidance or resources that I can share with her to ensure she gets the support she needs? with the distance between us (we are long distance) I'm not sure where I can go for help. We are both minors living with our parents and I don't believe her parents will help her with her issues.
