Earlier this week, we reported that former “Duck Dynasty” Star Sadie Robertson had tested positive for COVID-19 after announcing that she was pregnant with her first child. Now, the 23 year-old is opening up about her “dark” battle against coronavirus.

On the latest episode of her podcast “WHOA That’s Good,” Sadie sat down with her mother Korie and her younger sister Bella, both of whom also tested positive for COVID-19. During their discussion, Sadie said that some of the most difficult parts of her illness were the sadness and depression that she was left dealing with.

“All the physical pain on top of the loneliness of it, the isolation of it, makes you feel this depression that is something that I’d never experienced before,” Sadie said, according to Entertainment Tonight. “I’m not going to lie, I cried a lot.”

“It’s really a dark sickness,” the 23 year-old added.

The family said that Bella, 18, was the first to get sick, with Korie, 47, testing positive next. Sadie explained that she had initially tested negative, but when her husband Christian Huff got a fever, she realized she was definitely going to get sick too. Sure enough, that’s exactly what happened.

“Two days later I was full-on COVID,” Sadie said. “Mine started with a really bad headache. Like, a different kind of headache than I’ve ever had — it was like a migraine behind my eye. Then I got the cough, my throat was so red and on fire. It was terrible.”

Sadie’s symptoms quickly escalated to a brain fog, body aches, a loss of taste and smell and difficulty sleeping, despite being “so tired.” Things got so bad that she eventually had to go to the hospital.

“Being so weak and so sick and throwing up as much as I was, I got very dehydrated,” Sadie said, adding that on top of that, she was dealing with morning sickness from her pregnancy. “At this point, when I was dehydrated, my chest pain had gotten really bad. I could barely talk and Mom came over and was like, ‘You need to go to the hospital.'”

“I just remember you looked so pitiful and your voice was so weak, you could not talk,” said Korie, who went on to add that the moment Sadie went to the hospital alone was the moment Korie “knew she was a mom.”

“She’s not just thinking about herself,” she said.

Sadie concluded by urging her fans to take coronavirus seriously.

“I am a very healthy person, I exercise a lot and eat pretty good. I take care of myself. I honestly thought if I got COVID it would not be that bad. But no, I had it horribly,” she said. “So don’t think you’re just going to be fine… it is a really tough sickness that you don’t want to get.”
