Am musing about whether even posting this is a good idea, but maybe I'm in a sufficiently good place to start this thread, and it may help others in future.
I've looked at the other threads, and realised that when my dd was diagnosed with anencephaly, I wouldn't quite have fitted in either. I have wished many times that her lesion had been further down her neural tube, so that she would have been disabled but alive.
But we didn't choose to let her live her natural life-span, however short - we had her induced at 21 weeks, so yes, a termination. I'm surer now, since going through that, that if she'd had a chance of survival we'd have clung to it, as losing her was so hard, even though she had weeks, maybe a couple of months to live.
So, for those of you whose unborn child has recently been diagnosed with a lethal condition, or who have terminated or carried such a child to term, maybe this thread will help you - I don't know. Personally, I hope it's quiet, and nobody else has to go through it. But if you do, here it is, and here I am.
