Maybe I can start, if that's okay.
I think you raise really interesting points that are relevant not only to eating disorders but to other types of mental illness as well. That's why I feel it's important to look at this issue in context.
The Mental Health Commission of Canada has launched a campaign around stigma. I think these are some of the things you may be addressing: how parents are very reticent to talk about it among their neighbours, how even a young adolescent may be reluctant to share that kind of information, and they may not understand that their symptoms are being pondered by their friends. So one of the things that the Mental Health Commission of Canada has done is a stigma campaign called Opening Minds.
One of the things they've done with Opening Minds is they've tried to address the plethora of mental illnesses through reducing stigma and discrimination, and to be able to talk about these types of issues very openly, so that as a society we start to get comfortable with understanding that even though we label things as disorders or illnesses, that our mental health and well-being is no different than our physical health and well-being, and nobody should be suffering in silence.
They've approached this issue by speaking with allied health professionals, by addressing issues of stigma within the media, for example. Their interim report just came out in November, and they talk about some of the best practices involved in trying to better de-stigmatize some of these issues around mental illness and disorders.
