Hun, I know EXACTLY how you feel. When I miscarried, I got a lot of, "You can always have another," and "Everything happens for a reason."
Talk about damaging things to hear. I don't want another one, I want the one I lost! And who says I was SUPPOSED to loose my child? It's not me starting my period late, its my baby dying!! It feels like it is brushed off a lot. After two weeks, people think I should be over it. I'm not. I won't be for a long time. I am going to cry, and hurt, and feel that loss many times over. My husband's stepsister has gone through countless miscarriages, so he has some clue, but at the same time he is a guy and just doesn't get it. No one who has not lost a child understands.
You are allowed to grieve for as long as you need to, everyone else be damned. I do a lot of writing about it. Some of it is on my myspace page, myspace.com/ivydragonwind.
Strangely, sex helps a lot. Good, frequent sex. Orgasm is incredibly healing and stress relieving. I have made it a daily routine after my miscarriage, and I am not trying to brag, because most of the time I don't get 'help'

, but my brain has seemed to rewire itself to run better since. Sex helps chase away the demons the loss has left behind.
Also, I bought some things for the baby after she died. A few clothing items that made me think of her. It was good to finally acknowledge her, instead of trying to 'move on' and forget. I only had her for a little while, I don't even know if she was really a she, but it seems right. I didn't name her, but she was my little girl just the same.
