Michelle,
I am so, so sorry for your loss. Reading your post almost brought me to tears as your words could have been my own. I had a similar episode just over 2 weeks ago. Nothing can describe the shock,pain and heartbreak of finding out like that when it is supposed to be such a happy event seeing your baby for the first time. Mine was in there but just still and floating with no heartbeat . I would agree that it was probably the worst day of my life -even though i had had a prior m/c (was not as far along and not quite so traumatic finding out). I wish I could tell you something to ease your suffering but sadly there is nothing that anyone can say or do other than to be there for you. We sought some councelling which has helped both my DH and I, as has finding this forum -even if it to just vent all your feelings and realise you are not alone. I am told with time there will come hope for the future - I will admit to have not quite found that yet myself but I do know that i will try again. That desperation to have children really does overcome most barriers.
Please take care of yourself and take time out from daily life if you need.
Let us know how you are doing.
