During the episode, the OWN Network owner asks the best questions that get right to the heart of the matter. "That struck me, the brutality of loss," Winfrey expressed to Sandberg, according to Essence's exclusive first look. "How are you learning to breathe again?" she asked.

"I'm learning to let the grief come when it comes, to lean into the suck," Sandberg revealed. "We get upset that we are upset. I get angry that I'm angry. I settled into the feeling and it began to pass more quickly."

The discussion is a moving reminder that all of our emotions are valid.

Sandberg's interview with Winfrey on Super Soul Sunday airs this Sunday, June 25 at 11 a.m. ET on OWN: Oprah Winfrey Network. Mark your calendars and get your tissues ready—this talk is not one to be missed!
