Stone is feisty and passionate about helping women who are suffering or have suffered from a perinatal mental illness, saying she would throw herself on a fire or in front of a bus to help moms. But when she talks about her daughter Madden, who is now 8, the emotions break through her steely resolve.

"When she has a baby, if she has a baby, she's not going through what all these women go through right now," said Stone, fighting back tears as she recounted the suffering of women, including her own mother and grandmother, who have experienced depressive episodes around pregnancy and hated themselves for it.

"My daughter's every daughter. Every mom out there should be concerned about this."
