More important to the issue of post-partum depression in my mind, isn't so much self-recognition, it's barriers to treatment.
A huge one being "failing" as a mom and the stigma.
The other one being how pill-o-phobic people are these days, especially if they are breastfeeding (and even when they're not).
Maybe it's just because I live where the hippies have won and measles, pertussis, flu, have come back in a big way. I'm waiting for polio now too.
No medical interventions, and only crystals and herbs allowed. And I just put this together, like, why are people rejecting medicine that actually does something?? For that reason. It does something, and that's scary because of all the feared side effects. Never mind that most of the time, the disease IS worse than the cure. Crystals and herbs, besides their appeal as appeal to nature, basically don't make you feel jack shyte (apart from when your condition worsens, or all those herbs put you into liver/kidney failure) besides maybe some placebo effect. It's very difficult to compete with placebo from "natural" when you also have nocebo if not actual side effects from actual interventions.
