Helping someone else?

Haven't been here in a while. In my previous posts I've probably mentioned a friend that ghosted me. We became friends again a few months ago and are stronger than ever. But now, she's going through a hard time in her life, her other bestfriend is avoiding her, she feels fat because of her PCOS and she hasn't gone to school in three months. I live in a whole different country now so that makes this a little harder since I can't talk to her in person. She feels isolated and incredibly unloved. Do you have any advice I could give her? I hate seeing her suffer so much, so I'd love any advice I can get.
