Jealousy and Loss

My fiancé and I had a miscarriage a couple months back. It was really hard because the both of us really want a child of our own, even before we met each other. Just the other day, someone very close to him had a beautiful baby boy. I will always be happy for someone who brings a new life into this world, but I couldn't help but feel insanely jealous; most sad. Just seeing another woman with her own baby makes me feel really bad about myself. Does anyone else feel this way sometimes...?
