My days veer between being depressed and on top of the world. I've always been susceptible to mood swings but this erratic behavior is unnerving. My husband mildly criticizes the Tandoori chicken I made for dinner as being too chewy, and I'm flooded with tears. After consoling me for an hour and assuring me that the chicken was delicious even if a tad chewy, he finds me rolling on the floor that night watching a rerun of 'Friends'. He shakes his head, baffled and unsure of what to make of the ten-headed alien that's entered his wife's body.
