Rage in pregnancy

How do you cope with your rage while parenting? 

Some days I have to control myself from just absolutely losing it on my kid. I’m currently 32 weeks pregnant and have a almost 2 year old.

And I find that I get so emotional when something happens that I just turn into a psycho. Some days I have to walk away and literally scream and shake to get my frustrations out in another room.

I need help controlling this any suggestions would be helpful.
