I'm not so sure broadcasting to the world that she is mentally ill is going to be all that helpful in finding this teen or in getting her to return voluntarily.

First- there shouldn't be a stigma attached, so I don't like the assumption that this is something shameful or humiliating for her, and
Second- how is this different than every other missing person's case I've seen on here? Many of the bulletins and fliers list known medical conditions including mental illness.
This is the first case I've seen here where releasing that info is met with criticism, usually posters are complaining the family holds out on releasing those sorts of details.
I hope she is found soon.
