I watched the first half of it.
The angle seemed to be that while it is grossly overdiagnosed, it is also terribly under-reported, and unfortunately, misunderstood. It showed how broad the spectrum is.
It had a severe case of a woman who was plagued with voices. She was depressed, had low self esteem, and had attempted suicide twice. The day after her second suicide attempt, the voices told her to kill her 6 year old.
She did.
She was diagnosed from prison, where she is serving a 40-something year sentence for 1st degree murder. She spoke openly about it, and it was heartbreaking to watch. You could see the pain in her face, knowing that she may never be able to forgive herself, but she knew that it was not "her" that did it.
As I've read so many times on this board, those with bipolar tend to go into another zone before they fly into a rage, and while they know they are not themselves, they cannot seem to stop it.
It was very sad, and very eye opening.
