ivillage has online support groups.
I'm so sorry.?
The Compassionate Friends...
I am so unbelievably sorry... ((hugs))
I don't know of any either, but I am very sorry for your loss.
Edited to add: I remember chatting with you when Jack was an infant. My DD had open heart surgery too, and I remember we'd catch up and "chat" on the Knot/Nest every once in a while. Again, I'm so incredibly sorry to hear that Jack has passed. You and your family will be in my prayers.
Our hospital offers grief counseling, as well as Hospice/loss meetings for parents who have lost children. Can you check into that?
Also, I think the miscarriage/pregnancy loss board here has some great women who are super supportive....I came across that board while searching for advice about a friend who had a miscarriage, and they are wonderful.
There are other resources out there that can help too, if I come across any, I will send them along....
