I don’t know your relationship with your daughter, or how dire of a situation they are in, so I don’t know how applicable my advice will be. Or what you’ve tried already. But I think you need to talk to her like an adult. Try reasoning with her, make sure she has all the information on what that would entail. Make sure she knows the consequences of her disorder if she doesn’t get help.
It’s hard trying to get people to go for help, and it’s hard to change the minds of disordered people, because it’s not always them that you’re talking to, sometimes the only part that listens is the disorder. I think you just have to keep trying, because one day you will find the right words, or she’ll be in the right mindset or some tiny little thing will be just perfect and she’ll agree.
It’s her choice in the end, and you have to treat her like the adult she is. I hope this helps a bit, and I really hope that she finds it in her to go for help.
Best of luck
