Hey girlie, I saw your post below about the PPD stuff for school and wanted to pass along a recommendation. I don't know if you've ever checked out dooce.com, but it's a mommy-blog that I read on a near daily basis. She went through hell and back with PPD, and even wrote a book about it. I don't know if you'd be able to use it as a source or anything, but it might be a refreshing read after all the snoozy clinical stuff.
Good luck!
