Yep. It totally coincides with my period. I have been keeping track of this stuff for nearly two years. It is full blown nasty PMDD. I go from feeling cheerful to feeling utterly suicidal and it was freaking terrifying at first because I couldn't figure out why it was happening. I would have crying jags and so on. That has never been my thing.
So tomorrow I go to the doctor and say, "I need an IUD or something to chill this shit out."
