D.,
I didn't respond to your original post, but wanted to give you hope.
My neighbor has Type 1 Diabetes and she has 3 children. No health issues with any of them... unless you count running around like maniacs a problem
I lost 2 pregnancies in a row. One at 20 weeks, the other at 16 week. I don't have diabetes and they don't really know what happened. But the 3rd time was a charm and I had a baby, then another one the next year, and another the next year for a total of 3 kids.
Unfortunately, nothing took away the sadness for me till I had the first baby. I hope you have better luck with that, there are more support groups on-line now than there was for me 18 years ago.
Friends and family never know what to say and usually say the wrong thing, but remember that they are trying to help. I suggest buying a little desk or table sign that says "Silence is Golden" because sometimes it is better to say nothing. Maybe they'll think twice before speaking if they saw a little reminder.
Good luck, I'll say a prayer for you and keep posting on mamasource when you need too.
