So frustrating!! 😤

My emotions are going crazy and honestly it's a little embarrassing. I freaked out and snapped on a worker at the store today he wouldn't stop staring at me because I was getting a little bit grumpy with my husband! I got so mad that I yelled at her and left the store. I was never this emotional with my first two pregnancies. By the time my brother in law came over today I just stayed away from everyone because I was afraid I would snap again. I feel so bad that I was so mean that I cried all the way home! How do I keep myself on check, I hate acting so irrational
