The latest teaser trailer for “My Big Fat Fabulous Life” is very anxiety-inducing. Apparently, Whitney Way Thore has decided to push through with her Whit-A-Thon and things aren’t looking good for her.

TLC released a sneak peek at an upcoming episode of the reality series earlier this week, and it shows Whitney frantically screaming as she does rappelling on her own. Something may have gone wrong as she was descending from the cliff because she lets out a loud scream before the trailer turns completely black.

At the start of the clip, Whitney did say that she was “scared out of my mind” while discussing her Alaska trip. The new adventure was planned by the television personality herself after failing to complete the Hawaiian 8K race. Though she’s now very eager to prove herself, she’ll come to realize that she may be pushing it too hard on this week’s episode.

The “My Big Fat Fabulous Life” teaser features scenes of Whitney doing some really intense activities. But she seems distraught in all of them, especially when it came to going down a steep cliff. “I came all the way to Alaska to do this [but] maybe this was just not a good idea,” she admits in the voiceover.

Based on an Instagram post, however, it seems fans don’t really have to worry at all. Last month, Whitney shared a couple of snaps from her Alaska trip and she proudly shared that she and her team completed the Whit-A-Thon.

Whitney even gave a shout-out to her trainer, Thomas, who helped her accomplish the challenging task. In a clip shared by TLC on Youtube, Tomas appeared to have struggled a bit in establishing a good connection with Whitney since the latter was reluctant to listen to him.

Meanwhile, Whitney is seen hugging and smiling with Heather in her latest Instagram update. Whitney’s BFF went to Alaska just to show her support, and this delights the TLC star. She even wrote in her caption that Heather and mountains “make me very happy.” She also encouraged her fans to tune in to see the rest of her Alaska trip on this week’s show.

“My Big Fat Fabulous Life” Season 6 airs Tuesdays at 8 p.m. ET on TLC.
