"I'm the only one in, of my siblings, my mom and my family that hasn't been affected by Lyme disease," Gigi shared, getting choked up. "It's been really hard for me because I'm the only one that doesn't really understand it."

"What's been hardest for me is just trying to find a way to be their hope and kind of be a strength for them even with the disease that I can't understand fully because I haven't been through it," Gigi continued.

Bella added that what keeps the family together through challenging moments is how much they support each other.
