C.M.
I'm sorry to hear of your loss. I too have experienced the heartache of losing a baby while watching others go on to have theirs. In one specific case, it was my neighbor, whose backyard is kitty-corner to mine.
We found out that we were both expecting, 6 weeks along, with due dates only days apart. Soon after, I lost my baby. The rest of the summer, I watched her as she worked in her yard and around her house- her belly growing nice and round while mine was empty. (I'm sure you can relate to the feelings I experienced all summer long. I actually felt physically ill.)
I continued trying to become pregnant again, to "catch up" to her- and where I was "supposed" to be- but month after month, I failed to conceive. I was in such a hurry to get pregnant again that I began taking my temperature, buying ovulation predictor kits, and timing intercourse- all to no avail. I became so consumed with the process that I experinced a great deal of stress and depression. Finally, a visit to the doctor confirmed what I suspected- I had stopped ovulating altogether.
It all culminated one cold October morning, a week before my due date, when I watched the flurry of activity and excitement at my neighbor's house, as family gathered, and she climbed into the car with her husband and her pillow, headed to the hospital. At that point, I let go. The "race" was over. I finally accepted the fact that she was having a baby and I was not. I made a decision to be happy about the pink balloons floating on their mailbox, and love the little baby girl- although she was not mine.
I'm not saying that you should "suck it up" and choose to be happy for your friends right now. What I am saying is that I've been in your shoes and I know how hard it can be. I also know, having been there, that it will get better in time. I would advise you though, not to become obsessed or bitter over your situation. Making the decision to focus on others' blessings rather than my own misfortune was the only thing that saved me from years of unhappiness.
In the end, the very next month- when I quit caring, quit trying, and the "little dark cloud" had lifted- I did become pregnant again. Although I have gone on to have several more babies since, I still look at my neighbor's little girl and wonder about mine. Nothing can replace that part of me that was lost, but I accept that and move on, knowing that the experience has changed me for the better.
You may continue to struggle around your friends for some time- especially until they actually deliver- but the key to moving on is in acceptance. Only then will you be able to find true peace and happiness.
I wish you all the best.
