Does n-e1 about being emotional/stress/bbyblue

I'm 31wks & since I was about 27wks I have been feeling all stressed and emotional..I can't think or talk to anyone with out crying..this is way out my comfort zone..I cry if I feel someone is trying to be mean to me..i have been holding all this in & not sharing with no one..I've notice it's making me sick..so that's why I'm seeing is anyone else having this..I feel this is because of the baby..so I want her out already.. & don't want to catch the baby blues either..
