I'd like to announce that I'm upset

Amanda • I live in Nebraska with my amazing husband, Ryan. We got married in August 2015! Having a difficult time TTC.
Just found out that my LITTLE sister (20 years old) is going to have a baby. Her boyfriend already has THREE children with THREE DIFFERENT WOMEN. My sister JUST moved out of my parents house last week, she's currently on probation for a DUI that she got two months ago.
My husband and I have been trying to have a baby but it hasn't happened. I'm so frustrated, all I can do is sob.
THIS ISN'T FAIR!!!!!
