Family support advice

Hello. I apologize if this is off topic. My wife suffers everyday with bulimia nervosa. And I am looking for resources and support networks. I spend lots of time online trying to educate myself on how best to support her and I do my best. But ultimately I am scared to offer too much advice as I am no medical professional nor her therapist. I am nonjudgmental, caring, empathetic, and generally full of optimism. But these are really trying times and I feel I need some new solutions and support if I am going to continue to be there for my wife. And unfortunately, we currently live in different countries so it puts a strain on how I can be there for her, and how we communicate. Thanks
