I know exactly how you feel Didi, I thought I coped so well with my last m/c too at the time, but it hit like a ton of rocks a short while later and hit really hard!!
I get what your saying re other friends getting pregnant and trying to stay happy for them, its so hard when all you want is one of your own
I had a heart breaking moment the other day in the supermarket, a youngish couple with a handful of kids and one little one crying his eyes out, I don't know why and perhaps he was being a brat, but the couple were so mean to him and really verbally not nice and I felt so sorry for the poor little mite and I just couldn't help think that they don't realise how lucky they are - what some of us here wouldn't do to have a wee one crying there eyes out in the supermarket! Breaks my heart sometimes.
