Just to help others....my wife was diagnosed with Severe PPD within a week of the childs birth.
She refused any help and was told by her family that she was fine.
She has since spend time in several mental institutions and the last diagnosis was Undifferented Schizophrenia, non-responsive to medication.
It has resuleted in a very nasty divorce / child custody issues and it NEVER should have happened.
I did all I could to help her but when you NEVER accept anything as wrong and your family backs you up, there is no real hope.
If I can ever help anyone else....just let me know.
