Since this is your daughter's condition rather than your own, it is respectful of her privacy to share only with people who can be trusted to treat the information and situation with respect and privacy. If your daughter wants the information "out there", at her age, that really needs to be her call. I don't see that as an issue of stigma, just one of respect and also of safety. You are dealing with something much more complex than a broken bone or diabetes in that this is not purely a medical issue. It involves emotions and triggers and pretty delicate balancing of many different facets. You can talk about a medical illness or a car accident or a broken bone with pretty much anyone because their talk about it or reaction to it isn't going to make the medical illnes or broken bone worse, but people's reactions to issues of mental health can be quite damaging if those reactions aren't supportive and helpful. We do have to be careful of that. For me it isn't so much a matter of stigma or hiding it fromt he world but of self-care, or in your instance looking out for the overall care of your daughter.
