Your reactions sound absolutely normal to me. The time of my EDD was really hard. I thought I was coping well and then it just hit me again, and I didn't have a friend announce their pregnancy like you. Perhaps she's just not sure how to approach it with you knowing you had a m/c and now she is pregnant, and is trying to protect you from more hurt by downplaying her joy with her comments??
I've been through phases of wanting to talk to just wanting to keep things to myself and try and sort through emotions on my own. All you can do is what is right for you at the time. I also struggle with talking to family sometimes too. It's hard enough figuring out how to deal with things or my own frustrations and disappointments let alone having to explain to people who haven't been there.
As for moving through, I think time will help and not being too hard on yourself also. What you are feeling is normal, and you need to let yourself grieve for your loss.
