In this clip from the episode, Brie makes a heartbreaking confession about her husband.
"What a lot of people don't know about my husband is he's been battling depression since he was 25," Brie explains. "And really our whole relationship I've been used to his depression, but definitely in the last two years I know, OK it comes, it hits hard, but it only lasts for two days."
Brie continues, "I've always told him, 'Go to therapy or see someone.' And I've always left it for him to decide who he wants to tell, how he wants to tell people."
