Shabs, keep remembering that book I told you about. It really would help show Dan and Em that PND has all manner of symptoms and all ways of showing its ugly head. It is based on case studies of totally different women in totally different situations.
The good thing is the chapters are fairly short and so easy to pick up and put down (PND can leave you feeling so unable to concentrate that you can't cope with thinking about too much. I sometimes felt my head was bursting full with nothing.)
Even if Em isn't ready to read it, it might benefit Dan. IIRC, there is a section from a partner explaining how he felt.
Pazza has it and I think she's read it.
Dan needs to fight this corner. No one can make Em see life differently but he alone has the right to push for what he believes in. What we don't want is for Em to feel like everyone is ganging up on her. If its Dan alone talking to her, I think that talking she might feel less overwhelmed.
Shabs, I'm not sure its anything to do with the house/labour. FWIW, I personally, felt my hormones were smashed to smithereens and it took them a year to 18 months to begin feeling normal.
Keep posting sweetheart xxx.
