Jennifer Lawrence is opening up about the realities that come with motherhood and how it’s affected her work.

The “Passengers” actor stars in a new film, called “Die My Love,” in which her character develops postpartum psychosis after childbirth.

Lawrence, who now has two children, spoke about how her own experience with having children informed her process.

“As a mother, it was really hard to separate what I would do as opposed to what she would do. And it was just heartbreaking,” Lawrence said of her character at a Cannes press conference for the movie, according to Variety.

“I had just had my firstborn, and there’s not really anything like postpartum. It’s extremely isolating, which is so interesting,” she said, before again talking about her character’s experience in the film.
