I'm being such a b**** to everyone

Megan • 24, have a 6 year old girl and an amazing boyfriend! Expecting #2 November of 2015!!
I don't know if its all the stress I'm going through like finding a new house and moving and or the hormones. I feel bad for my family Bc I have a huge attitude lately. Then I get emotional..it's a roller coaster! I wasn't like this with my 1st. Anyone else feel similar? I'm 11 weeks.
