07/06/2016 AT 08:50 AM EDT  Forget feeling embarrassment – Whitney Way Thore is only feeling pain when she  in the shower and needs her roommate to come  In this exclusive clip from Wednesday's episode of  , Thore is mid-shower when she asks her roommate, Buddy, to help her into bed.  "I knocked my shampoo into the tub, so I bent over to get it, and I felt a pain I haven't felt in my back since the first time I hurt it," Thore, 31, says in the clip. "The whole lower back is in pain. And the thought of getting from inside the tub to my bedroom is impossible."  In her time of need, Thore is happy to have her roommate there – even if Buddy is less than excited to save a mostly-nude Thore.  "It's moments like these that I'm really glad I have a roommate because if Buddy were not in the house, I don't know what I would do," she says. "I think Buddy is probably not happy that he has a roommate in this moment, because I cannot wrap a towel around my body. I mean I don't own a towel that covers my body. So Buddy has to kind of justâ¦witness that."  "I can't say that I mind being naked in front of Buddy, but in this instance, you feel vulnerable since you're hurt, so I do feel weird in this instance being naked in front of Buddy." And in retrospect, the 370-lb. Thore knows that her size is at least partly to blame for her back issues.  "The last time I hurt my back I was incapacitated for a couple weeks," she says. "I think my back problem is directly related to my weight. I doubt that my lower back would have problems if I wasn't this fat."  Her back causes Thore to confront her weight issues again later. Unable to walk and dance in this year's St. Patrick's Day parade, Thore instead has to ride an electronic scooter, and faces major fat shaming from the crowd.  Thore deals with this and more in Wednesday's episode of  , airing on TLC at 9/8c.
