Elizabeth, 17, was diagnosed with cystic fibrosis when she was just 4 years old.
The hereditary disease produces thick mucus that clogs the lungs.
Elizabeth's condition is severe, and last month she was flown from Fresno to Lucile Packard Children's Hospital Stanford while she awaits a lung transplant.
The teenager is now blogging her experiences, hoping others with the disorder will realize they're not alone.
"The whole time you're just struggling to breathe. Like, that's not a very good time being spent," Elizabeth said. "So, if I can struggle to breathe but also be doing something really, really useful and helping people, then I be won't be just a person who lives and dies with CF; I'll be a conqueror."
There is not currently a cure for cystic fibrosis, but Elizabeth hopes her blog will also help raise money for research.
