I wish I could blame that time of the month. If cyclic hormones had seized control of my tear ducts and all of this was entirely normal, I'd feel less insane. But the scientist part of my brain demanded proof. Sadly, after searching PubMed, I could really only blame my period and the corresponding hormonal fluctuations if I were taking hormones (e.g. on the pill). That's not to say my hormones aren't raging out of control or that I didn't get a kick of prolactin anyway, but I concluded this isn't PMS. That was actually an obvious conclusion, since the P stands for "Pre" and not Post. And because I've been doing this whole monthly thing for long enough to know it's not a normal cyclic thing for me.
I'm not pregnant. I'm not menopausal. I'm not particularly sad. So what the hell is wrong with me these days!? I was about to go search Google and PubMed some more, but the UPS guy is at my door and that has me a little verklempt.
