I've just spent a lovely couple of days with a friend I've not seen for a couple of years. She has a four month old. The first evening I was there she mentioned being loopy after her birth, to which I replied "...yes, I've been there" and she challenged "No, not like this." the conversation soon covered my being sectioned and she explained that after the birth of her baby she was discharged -with medication- as she knew what was happening and had asked for help. Her episode is undiagnosed and presumably not a statistic. She firmly believes that plenty of women suffer from PP to differing extents and fall under the statistics radar.
She felt really glad to talk to someone she considers 'normal' that had experienced something similar.
In six years I've never talked to anyone outside of the MBU I went to with a similar experience. I thought one in a thousand was a reasonable statistic?
