In September 2017, the “You Oughta Know” singer told PEOPLE she struggled with postpartum depression months after her daughter was born.
“There are days I’m debilitated to the point where I can barely move. As a kid, I imagined having children and being with an amazing partner. This is a whole other wrench I didn’t anticipate,” she said at the time.
Morissette experienced PPD with her son, as well, and told PEOPLE the illness set back in “seconds” after she gave birth to Onyx.
“It’s very isolating,” she said. “I’m used to being the Rock of Gibraltar, providing, protecting, and maneuvering. It had me question everything. I’ve known myself to be a really incredible decision-maker and a leader that people can rely on. [Now] I can barely decide what to eat for dinner.”
