When asked about the hardest part of her cancer battle, Johnson cited undergoing chemotherapy, losing her hair and being unable to attend high school with her friends.

"I had to social distance throughout that because of my low blood count," the teen from Pasadena, Calif. continued. "So, in a way, it prepared me for this because at times when I wanted to see my family and friends I couldn't see my family and friends."

Thankfully, Johnson is now "feeling great."

"A week after the [viral] video, I went back to [Children's Hospital Los Angeles], and I got some scans and they were all clear. So, I'm cancer free," she said.
