"I'm so bummed," Sasha, 21, said during a Tuesday appearance on Good Morning America. "I really am, like, uncontrollably bummed."
The Pretty Little Liars actress and Gleb were eliminated from the Season 25 competition on Monday's "Disney Night" episode after they received 24 out of 30 points from the judges for their Little-Mermaid inspired rumba, placing them in a tie for eighth place on the leaderboard out of 10 competing couples.
"But I'm honestly so thankful for the opportunity, and grateful, not only to have made an amazing friend out of this, but also just to be able to share my story with everyone," Sasha said, referencing her new pal Gleb.
Sasha used her time well on Dancing with the Stars, as she revealed her two-year battle with polycystic ovary syndrome, or PCOS -- a hormonal disorder that caused her to gain 70 pounds -- in order to reach out to women in a similar health crisis.
"The reason I did it is because if I could just help one person, that would be amazing," Sasha explained.
"And the reaction has been awesome; people have been sharing their stories. Support in general is awesome. It's not taboo anymore. That was my whole point, just to get people talking about it."
Sasha pointed out that Dancing with the Stars aided her recovery from the syndrome. During Monday night's show, she disclosed the fact she had lost 37 pounds just from rehearsing and performing with Gleb.
"It's been amazing to feel like myself again," Sasha noted. "And to have that recovery and have people supporting me is honestly more than I can ask for. It's awesome."
But just because their time on Dancing with the Stars together has wrapped doesn't mean they are going to stop dancing together. Gleb revealed that he's going to choreograph a wedding dance for Sasha and her fiance, Hudson Sheaffer.
"It's going to be a mixture of different styles," Gleb said. "I'll teach [Hudson]."
The actress and Gleb then predicted which celebrity and professional pairing has what it takes to win the Dancing with the Stars season.
While Gleb acknowledged leaderboard-topper and Broadway star Jordan Fisher is "incredible," the pro dancer admitted, "But my pick would be Frankie and Witney."
Sasha agreed that Frankie Muniz, an actor and race car driver, and his pro partner Witney Carson are the frontrunners of Season 25.
"They are so great," Sasha said.
"Yeah, they're so good," Gleb added. "[Frankie] is amazing, and every week he is improving and I feel like they might go all the way and get that mirrorball [trophy]. You never know."
