According to Nikki Morrison (our resident Nurse, Death Doula and Angel), Premenstrual Dysphoric Disorder (PMDD) is a medical condition similar to Premenstrual Syndrome (PMS) but it's a kind-of, ‘on steroids’ version. PMDD causes severe (sometimes extreme) irritability, depression, pain and/or anxiety in the week or two before a period starts. For Nikki, extreme PMDD led her to question her sanity, her future, her ability to keep working, to have relationships and even, to leave the house. For me, this was an eye-opener on a range of levels. Enjoy.
