I am so mad...

In November I went through my first miscarriage... my heart was and still is heart broken about it. I want a baby so bad. I find myself getting mad or jealous about my friends announcing they’re pregnant. Me and my husband told a few people about the pregnancy because we were really exciting and eager and the people we told were excited for us but unfortunately I lost the baby. Well today one of the people that we told announced she was pregnant with her boyfriend that she has been with for about 2-3 months. I found myself being mad and jealous, losing all my motivation I had for today and just wanting to lay in my bed curled up, under the covers to cry... Why can they get pregnant but me and my husband can’t? I’m not sure what to do to help or get rid of these feelings...
