ITA with most of what you have said. However, some people compensate for their illness so well, that it is hard to know they are ill in the classic sense of the word. Obviously, Gia is not *ahem* well. She was probably cast for that very reason. Of all of the women in the house, her behavior has been the most outrageous - underscoring the rage in that word. Exploitation of her illness is what I call cruel.
We know depression can manifest itself in many ways. And, of all of the depressions, IMHO, post partum is the worst. While everything in nature is telling you that you should love your infant child, you are rejecting it. Result: Terrible guilt, self image destroyed - sometimes so severe that infanticide occurs. Unimaginable depression Psychosis. And, most men do not understand post partum depression (IOW - husband virtually useless). Women who suffer from that illness are to be pitied. Even Gia, if in fact this is true. She lost something she will never regain - a time that was meant for bonding with her child is gone forever.
Of course, we are assuming that this program has any basis, whatsoever, in Reality. But, interesting discussion, nevertheless.
