Our treatment for all forms of depression -- which includes how we hold space for people who are in depression and recovering -- is quite poor.
The go-to medications like Prozac and Paxil are a big part of the problem, because they aren`t actually effective at treating depression. They just numb people out emotionally. 
Someone I know who had severe post-partum managed to get in for electro-shock therapy. (Her MD had said electro-shock was bad and she should go on Prozac, which had no effect for the eight months of her previous postpartum depression.) 
She got the electro-shock and felt normal again after the first treatment. She followed up with the additional five, and had no recurrence of depression. Unlike the movie depictions, her  experience was comfortable and respectful. One of the nurses who helped set her up told her frankly that the medical staff she knew never bothered with drugs when depressed, but got themselves in for shock treatment.
