Premenstrual Dysphoric Disorder (PMDD) is a severe form of PMS characterized by intense mood swings, depression, and lack of motivation.

“PMDD is a severe form of PMS. Very, very common. Devastating for these girls. The best way to describe it is these girls, two weeks out of the month, they're perfect. Two weeks out of the month, they destroy all their relationships. They're depressed. They're crying. They're unmotivated. They don't want to go to school. they completely decline. They don't want to go out and two weeks after, so I always say two weeks out of the month, you destroy all all your relationships and then you spend two more weeks fixing it. And then the vicious cycle happens over and over again.”
