Selena Gomez has opened up about the fears she had after she was diagnosed with bipolar disorder in a teaser for her powerful new documentary, My Mind and Me.

Vanity Fair shared the tear-jerker clip via TikTok on Wednesday.

“When I first got out, I didn’t know how I’d cope with my diagnosis,” Gomez said.

“What if it happened again? What if the next time, I didn’t come back?

“I needed to keep learning about it. I needed to take it day-by-day.”

The star first revealed her diagnosis when she appeared as a guest on Miley Cyrus‘ IGTV show Bright Minded in 2020.

“Recently, I went to one of the best mental hospitals in America, McLean Hospital, and I discussed that after years of going through a lot of different things, I realised that I was bipolar,” Gomez said at the time.

“And so when I got to know more information, it actually helps me. It doesn’t scare me once I know it.”

In the doco’s teaser, Gomez spoke about how since she was a child, learning about the things she feared helped her conquer her anxieties.

“When I was a kid I was terrified of thunderstorms,” she said.

“I grew up in Texas and I was so scared that lightning and thunder would mean a tornado was coming.

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

It’s extremely poignant and, quite frankly, had me sobbing.

My Mind and Me will give fans a raw insight into Selena Gomez’s personal life. It follows the past six years of her life and shows the ups and downs she’s faced amid her rise to stardom.

You can watch the official trailer below.

“After years in the limelight, Selena Gomez achieves unimaginable stardom,” a press release from Apple TV+ stated.

“But just as she reaches a new peak, an unexpected turn pulls her into darkness. This uniquely raw and intimate documentary spans her six-year journey into a new light.”

The documentary comes from director Alek Keshishian, who also helmed the ’90s classic Madonna: Truth or Dare. Per The Hollywood Reporter, Keshishian said he didn’t want to make a cheesy pop doco.

“I wanted to show something more authentic and Selena did, too,” he said.

“She has a raw vulnerability that captured me. I had no idea then that it would become a six-year labor of love.”

There’s no doubt the documentary will be profoundly moving; Gomez went through a lot during the six-year period it follows.

As well as opening up about her mental health and seeking professional treatment several times, she received a kidney transplant due to autoimmune complications from a lupus diagnosis — a disease where the immune system attacks healthy tissues and organs — and cancelled a world tour to focus on her physical and mental health.

But there have also been beautiful highs in Gomez’s life, such as scoring her first-ever Billboard number-one single with ‘Lose You To Love Me’, starring in a slew of successful TV shows and movies, being a generous advocate for myriad social causes, and launching a truly gorgeous makeup line, to boot. The things I would do to get my hands on that Soft Pinch Liquid Blush.

The documentary will premiere globally on Apple TV+ on November 4.
