Selena Gomez opens up about her mental health in her upcoming documentary “Selena Gomez: My Mind & Me,” is set to debut on Apple + on Friday.

Ahead of its release, she sat down with Rolling Stone, where she talked about the “psychotic break” that lead to her bipolar diagnosis.

“I’m going to be very open with everybody about this: I’ve been to four treatment centers,” Gomez shared. “I think when I started hitting my early twenties is when it started to get really dark, when I started to feel like I was not in control of what I was feeling, whether that was really great or really bad.”

She shared that in 2018 she started hearing voices that eventually “drowned out more and more of the real world,” triggering a psychotic break. The singer was hospitalized and diagnosed with bipolar disorder.  After her release she worked with a psychiatrist to find the right balance of medication.

“But I had to detox, essentially, from the medications I was on. I had to learn how to remember certain words. I would forget where I was when we were talking,” she explained. “It took a lot of hard work for me to (a) accept that I was bipolar, but (b) learn how to deal with it because it wasn’t going to go away.”

Gomez shared that because of two medications that she takes she likely won’t be able to carry her own children in the future, something she said is “a very big, big, present thing in my life.” She added that, “however I’m meant to have them, I will”
