Tamar Braxton withdrew from Dancing With the Stars due to “serious” health concerns on Wednesday, and the upcoming season of her reality show promises to show “what really happened” as the performer’s hectic schedule ended up sending her to the emergency room.

“I’ve been dreaming of this moment since I was a little girl, but it’s a lot of pressure,” Braxton admits in a preview clip from season four of Tamar & Vince, her reality show with husband Vincent Herbert. “My schedule is out of control, as you can see.”

While Braxton always appeared cool and composed on DWTS, Tamar & Vince showcases the 38-year-old singer's behind-the-scenes moments, letting her nerves and insecurities show through, as she worries about how she is going to handle the press and pressure surrounding the release of her fourth studio album, Calling All Lovers, while also competing on the reality show.

When the whirlwind life catches up to Braxton, she stubbornly protests that she’s not sick, telling Herbert, “I feel amazing.”

“You don't want to push it,” her husband cautions. “You don’t want to wind up in the hospital.”

“Tamar is a perfectionist,” Braxton says of herself, speaking in the third-person. “I gotta take a deep breath and get it done.”

However, as the show ends with Braxton’s trip to the emergency room, it’s evident that her fast-paced life has taken its toll.

"With a heavy heart I regret to inform you that my season of #dwts has to come to an end along with the rest of my tour dates with @musicbykem," Braxton Instagrammed alongside a picture of her lying in a hospital bed with her pro partner, Val Chmerkovskiy on Tuesday. "After yesterday's final #dwts performance I went back to the hospital (after the doctors didn't want me to leave in the first place) only to find out that I don't have pneumonia but something way more serious and that is having several P.E.'s (blood clots in both sides of my lungs)."

Dancing With the Stars confirmed to ET on Wednesday that Braxton was no longer competing on the show. "We can confirm that Tamar Braxton asked to withdraw from the competition due to medical issues," the statement read. "Our pro and celebrity dancers' health is paramount. We wish her all the best and hope she recovers quickly."

The new season of Tamar & Vince premieres December 10th at 9/8c on WE tv
