Let me start off by saying I am sorry for your loss I know how you are feeling I had a missed miscarriage May '10 it was NOT easy at first but trust me with time it does get better I found that writing in a journal helped a lot and wanting to be alone is normal it will take some time to be comfortable around people and like Rstoppkotte said the worst part is people being insensitive but people don't know what to say if they never been through it and they are just doing what they THINK will make you feel better if you need anything my story,encouraging words or just someone to talk to I'm here and just remember you can and will get through this I hope you feel better soon
I'm so sorry for your loss. I had a miscarriage in Dec 08 and an ectopic Jan '10 so I can absolutely relate. Unfortunately, only time will heal your pain. My mom, who also lost several pregnancies, says she never got over her own grief until she had children. I can tell you it gets easier and the worst part will be all the insensitive people around you. They mean well, and you'd never wish for anyone to go through what you're going through, but sometimes they only make you feel worse. Also, if you can't conceive again right away, you'll probably resent those around you who are pregnant and having children. That's what is to come. In the mean time, open up to people who do understand and make friends on pages like this. For me, I couldn't bare to be around my friends for awhile, but now that I've started going out with them again, I've found them to be a great support system. If you're married, make sure to grieve with your husband. Whether he shows it or not, he's hurting too.
Best of luck.
