Yep I remember literally snatching my I.D. card back from some fellow at a science centre where I took my toddler, and hissing at him. I was medicated but in the thralls of postpartum exhaustion and moodiness. I actually received a letter from the science centre discussing my behaviour and the appropriateness of the employee asking me for the I.D. card. Oops. LMAO!!!!

One hallmark of my moodiness is the rages I can get into. It's not nice. I smashed a lamp in my kids' room one evening in a rage. I have to bang the walls with my fists sometimes to get out the anger that is a very physical visceral feeling.

So yeah. You're not alone.

ETA - good on ya for walking away OP!
