We Lost Ours...

Hello friends,
I need help and I don't know where to seek it. After over a year of trying to get pregnant, last week it was confirmed that we lost our little bean. It has been hell on Earth trying to live through the pain (both physical and emotional). 
While I can tell that my husband and I are starting to heal, I have one area that I cannot control and I hate the way it makes me feel. A friend of mine at work got pregnant almost exactly the same time as we did. She is much younger, is not financially stable, and I cannot help but be angry at her that she gets to keep hers and we don't get ours. I know it is not her fault. And I don't like the ugly feelings that I am having. But every time I see her, they bubble up and ruin me.  We deserve that happiness, and I am having a hard time dealing with why others get it and we do not. 
I need advice if you have been through this, or maybe just a positive word if you have not. Having a hard time seeing the light at the end of the tunnel.
