I can understand your sadness and difficulty with this situation,been there - although not with triplets.

As some of the posts above suggest - could you get your DH to ring on the behalf of both of you. Your post indicated he was dealing with this better so he's probaby the best one to ring. Or, perhaps you could send a card?

Do they know your difficulties in TTC? If so, just let them know somehow that you are happy for them but just need to time to come to terms with your own sadness that comes at these times.

Above all else, you have a right to feel sad, angry, frustrated etc. Your feelings are those many of us LT TTCers have felt and struggled with over time.

As for coping, do what you need to do to get through this. Find someway to treat yourself, maybe some retail therapy, pampering etc, and lean on those you know you can trust for support. Here's another just for you.
