Selena Gomez was unsure how to ‘cope’ with bipolar diagnosis

Selena Gomez is sharing some of the most personal details about her mental health.

The “Only Murders in the Building” star and “Calm Down” singer reveals what helped her rein in her concerns following her bipolar diagnosis, in a clip from the Apple TV+ documentary “Selena Gomez: My Mind & Me.” It comes out Nov. 4.

“When I first got out, I didn’t know how I’d cope with my diagnosis. What if it happened again? What if the next time, I didn’t come back? I needed to keep learning about it,” Gomez, 30, says in the clip, recently released via Vanity Fair’s TikTok account. “I needed to take it day by day.”

Gomez goes on to say that she was “terrified of thunderstorms” when she was younger, as living in Texas led her to fear they would give way to tornadoes.

“But my mom gave me these books for kids that … basically said, ‘The more you learn about it, the less you’re going to be afraid of it,’” she recalled. “And it really helped.”

The R-rated documentary — helmed by Alek Keshishian, who directed Gomez’s 2015 “Hands to Myself” music video — offers “an unflinching look at her mental health journey,” according to Vanity Fair.

This isn’t the first time Gomez has discussed confronting things head-on, noting in early 2020 that that method “took the fear away.”

“I realized that I was bipolar and so, when I go to know more information, it actually helps me,” she told Miley Cyrus’ “Bright Minded: Live” at the time. “It doesn’t scare me once I know it.”
