WATCH: Sheryl Sandberg Full Berkeley Commencement Speech

Facebook Chief Operating Officer Sheryl Sandberg shared an emotional and moving message with the graduates of University of California Berkeley during her commencement address on Saturday, speaking about the loss of her husband and what his death taught her about life.

It was the first time Sandberg has spoken publicly about her grief since her husband, Dave Goldberg, died last year.

“Today I will try to tell you what I learned in death,” Sandberg told the class of 2016.

“Dave’s death changed me in very profound ways. I learned about the depths of sadness and the brutality of loss,” she said. “But I also learned that when life sucks you under, you can kick against the bottom, break the surface, and breathe again.”
