Attack of the pregnancy hormones

I keep hearing about how pregnancy hormones can make a woman overly emotional, but I haven't noticed a big difference up until now. Let's face it, I'm a pretty emotional person to begin with, so getting weepy at sappy songs and commercials is nothing new to me. I might have been a little snippy now and then (sorry, Mom), but no major breakdowns until today. I had just dropped of Mom at physical therapy and was on my way out of the parking lot. There's a weird intersection in which half the cars have a stop sign and half don't. I was already frustrated because I was trying to wave another car on and he was just sitting there. A couple cars were starting to get backed up, so when I thought it was clear I started to go. I didn't see the woman BARRELING down through the intersection, and so brakes were slammed, tired screeched, horns honked. (No crash, but it was close). I knew technically I was at fault since she had the right of way, but she literally was going 50mph through a parking lot and came out of nowhere. Anyway, I threw up my hands at her and mouthed "SORRY!" Got out of the parking lot to the next red light, and proceeded to fall apart. Literally. I could not stop crying! I mean, head in my hands, shoulders shaking, sobbing! And I could not stop! It went on for at least 5 minutes, all the while I'm thinking to myself "This is ridiculous! You are fine! Stop crying!" It almost felt like I was not in my own body, like I was sitting next to myself watching me weep like a little girl. So bizarre. I've convinced myself that it's the hormones, and I'm not becoming a real crazy person.
