Anger and Crying

Carla • In love with my little family❤️ | 1st baby due Sept 27, 2016❤️
I need some help, Iv'e been feeling all types of moods toward my boyfriend. I end up hating him saying things I don't mean, which makes him mad and ends up saying hurtful things to me which makes me end up crying. Do any of ya'll have any advice that I can do that can help me relax? I really need it. It's important for me to try to keep calm so nothing can happen to my baby 😔 I try to not be mean to him, but idk how to control myself.
