Feeling empty!

Mallory
So after a very rough night of nauseating cramps and lots of bleeding, woke up and felt good as everything was done. Excited that it's my sons birthday ready to face the day. Well at work around 3 I felt a giant gush of blood, ran to the bathroom and saw I had passed my entire gestational sac. I was ok thinking it was over last night, but now that I have actually seen the sac I feel empty, hurt, angry, sad and so much more. Then find out that my so invited his mom, brother and the oldest nephew to our family dinner tonight. I snapped my mother in law is a very negative person and even though she says they are their for my son I know something will be said and I can't control my emotions. This sinter same women that told me a year ago after taking care of her in the hospital that I ruined my life and should give up on my dream of going to school because I got knocked up at 19. But my SO does not understand why I am upset. Am I being over dramatic? I feel bad because as soon as I walked in i started  yelling at him about it, but I'm just hurt
