Yes an ED always stays with you, the mental side of it anyway. But she is only 8 and im assuming she could be young enough to fight the disorder and grow up a healthy child.. however, if i were her parents i would still keep a close eye on her and would be a little concerned for when she got into her teenage years as the pressure to look good and eat healthy is much more, and by then she will understand more about how she feels about herself.
I hope though she kind of 'forgets' about Anorexia now.. so to speak. It said in the programme, in young people it can sometimes be a cry for help, and watching her, she seemed to be almost relieved to be able to eat when she was at Rhodes Farm, so i think she may take recovery well and carry on as a 'normal' child.
