One of the most upsetting off-camera Bachelor events concerns Britt Nilsson, who starred on Season 19 of the original series. Nilsson — in a brave move — revealed that she struggled with a bulimia relapse during the show.

Blaming the relapse on "pain and anxiety," Nilsson shared that she dealt with the eating disorder for most of her life. She said in a video shared to her YouTube channel: "For me, having tons of food everywhere ... it just became too much. ... I felt insecure, I didn't feel pretty enough, I didn't know what was going on, I missed my family."

In a heartbreaking reveal, Nilsson shared that she tried to conceal her health issue. "I was totally terrified that it was going to be caught on a mic and that millions of people were going to know that I just couldn't control myself," she added. "It was really, really hard for me, and it just kept going and going."

She continued: "You're mic-ed 24/7. I would take my mic off and try to hide it under towels so they wouldn't hear me throw up, because then that was going to be on the show and that was going to be a plot line."

Luckily for Nilsson, she has found support in her now husband, Jeremy Byrne. "He just stuck by me with it," Nilsson explained. "He would ask me about it, he would keep me accountable, and it actually got much, much better."
