People seem to have this mistaken impression that changing the name of something changes the way people feel about that thing. And while, this may work, to a small degree, some of the time, it certainly isn't the answer to a huge problem like the prejudice and discrimination seen against those with a mental illness.
Onset of serious mental illness in late teens and early twenties is very common and often shocking to the families that experience it. The medical community knows this; researchers know this; millions of families know this and yet we wait for the topic to find its time while millions try to cope. Surely we can do better.
