As someone who has had (and recovered from) an ED, I can definitely agree that it noticeably changes your appearance. Really takes the life out of your eyes.She used to look really cute and fresh but all of that has kind of gone because of her ED. I feel a bit bad to say it like that because it's a horrible disease and she is clearly struggling but it made her look haggard and old.
Not going to diagnose Amelia with one but the characteristics are certainly concerning and I do hope she can seek help and support
