So sick of everyone getting pregnant but me!!

Cassie • I am 1 in 10- PCOS fighter.
I have a friend who is 20 and already on her second baby. Another girl I graduated with just posted on Facebook that she's pregnant.  I was invited to a baby shower today but I'm not going because I'll probably cry. Why is it that everyone and their mother can make a baby but I can't. 
I really really really really hate PCOS
