Thank you all, I'm glad I posted.
I have also had the "Ah, she's just even more special now" comments from a few people and one family member said "It doesn't matter, she'll still be loved". Trouble is it DOES matter and I don't want a special child, I want a bog standard one with normal chromosomes. (I hope that doesn't offend anyone, hopefully you know what I mean).
Some of our close friends have been brilliant and we've been able to say exactly what we feel and they've not tried to make light of a shit situation.
We're in a better place now than we were when we first got the diagnosis. I really questioned whether I even wanted her. Possibly that was a bit of the PND too. But she is lovely and we do love her - we just absolutely hate her condition. It took me a while to make that distinction.
messmonster I may PM you at some point, thanks for the offer. DD's condition isn't quite as rare as your DD's but not a million miles off. You just think 'why??' all the time don't you.
I can only speak from my own experience but post-diagnosis I felt utter grief that the child I was expecting to have was not the child who had arrived in the world. I had no idea how many unspoken, subconscious hopes and dreams I had for my unborn DD until she arrived, was diagnosed and I realised that many of them were just never going to happen. As I write that, it sounds so horrendously negative but that is honestly how I felt at the time.
That is EXACTLY how I feel. Thank you for your honesty, it really helps.
Anyway, thank you all of you and here's hoping I can laugh again one day.
