I am so sorry for your loss, i really am.
As I was reading through your post you said you wanted to wallow in your own pain but couldnt. I was thinking that yes you can, if you want, maybe it's just what you need. But the other ladies beat me to it to say that. So I can only agree with what they all say. Take the time you need to deal with this huge loss the way YOU want to.
I also wanted to say that there is no reason why you can't go on to concieve again and have a healthy pregnancy. Although it is probably the last thing you want to think about right now. Are there any support groups/networks in your area you could access?
