Anorexia She started Uni in Sept. What can we do?

My partner's daugher (21 y.o.) is anorexic. She started Uni in Sept. Before going she saw her local doc who recommended counselling. He asked her to see a doctor as soon as she went to Uni (3 hours from home). She says she goes every week but I don't think she does(she was meant to go for blood test with first doc but she never went). I think that her weight is about 40kg and she cannot eat in front of people anymore. She is regularly sick for a few days (cannot keep the little food she eats). Her background: her mum died when she was about 10. Her dad did not cope well with it and was not there enough for her. She is closer to her dad now. I first met her 3 years ago. She was self harming and already had eating disorder. All that matters to her is her boyfriend and she doesn't have any girlfriend. In the 3 years I have been in the house, she has only brought a friend once. She spent the whole summer at her boyfriend's and that made it worse. What can we do so far away please? Thank you.
