Lake Bell fell into depression following her son's traumatic home birth.
The 40-year-old actress recently revealed how her and husband Scott Campbell's kids, Nova, now five, and Osgood, two, were born with the umbilical cord wrapped around their necks and unable to breathe and she admitted her youngest child's subsequent admission to a hospital intensive care unit made her stop feeling like herself.
She said: "I was like I need something, I can't be a person. I don't know how to be ... I had never felt that before.
"My heart aches for those who feel that through the hardship of their life every day, like, I have felt it. I know what it is and it's a monster. It's a demon."
Lake realised how low she had got one evening when her young daughter could feel she wasn't a "normal mommy" anymore.
