It's been coming and going for me. I cried AT work this past week because of multiple things that were happening all at once; I felt like I was going to throw up, I was cramping some, a student of mine was freaking out (kicking, spitting, punching) and I had to get all the kids away, and another staff member said something in a tone that I didn't like. I walked the kids down the hall and started bawling and had another staff member take over while I ran to the bathroom.
So yep! Thank the hormones :-\
