Thank you all again for great advice and comforting words of wisdom :)
And also for sharing your own personal experiences.
This is why I find MN so invaluable now I'm on maternity leave with a helpless baby!
Three weeks postpartum and I am starting to feel better every day. Oh yes, sometimes I think I can't possibly do this, but it passes. I am still tearful, especially if people ask 'how are you?' but I'm coping better.
(The trouble now is, that my DP thinks that every time I cry it's because I have PND and I need to seek help immediately..No, it's because I just watched RSPCA Rescue and I tend to wear my heart on my sleeve).
In retrospect, in life, when there's been a massive change, there is always a period of adjustment, and that period is often uncomfortable. But it eases. This is along those lines (albeit a HUGE change).
I admit, in the first weeks, I was wondering why on earth anyone had children. I couldn't believe that most people eventually have children- and hmmm, a small part of me still isn't convinced...but I'm getting there, especially when she smiles at me and grabs my hair.. ouch..
I know some people do find it easy but I think they are in a minority. I also think people who say everything's rosy may be fibbing.... 
Now the fog has lifted I am looking at my post baby body and I must admit I'm unimpressed! Did anyone else get a very flabby belly? Roll on the six week all-clear for some serious exercise.
I will use this experience to become more empathetic and keep an eye on my friends if they eventually stop being such massive pissheads settle down and have children.
