Danni says the diagnosis completely changed her life, as she was forced to give up what she loved most.
“I used to own my business as a hairdresser, but I got diagnosed and I couldn't do that anymore. So, that was a really, really dark place for me because I love hair," she said.
"This is not the life that I thought I was going to be living, but it's what I've got.”
While viewers didn't get to see signs of the disorder when Danni was on the screen, she explains they were definitely there.
“I have things like ticks in my body, my legs and arms don't have full function and they don't move properly. I have muscle spasms and I do have episodes, but I didn't have any in that house, which is good because it would be a bit confronting for housemates.”
Having lived with the condition for two years, Danni admits although it was “stressful”, she didn’t want it to stand in the way of going on the show.
“It was such a positive thing for me. So even though it was quite stressful, I was just so appreciative to be there.
"That kind of outweighed everything.”
However, she would have loved to have used the show as a platform to raise awareness about her condition and is disappointed her backstory didn’t make it to air.
“I think you don’t always see a disorder and whilst I might not look like someone that has one, that's usually that misinterpretation," she said.
“So, take the time to get to know the person, in your real life or in television. Don't always take it at face value, make sure you make the effort.”
