Meet Briana. She's a 19-year-old from Houston, Texas, who has a rare and deadly disease called aplastic anemia.
Though she's looking super cute and #HospitalGlam here, aplastic anemia is a very serious disease that affects only 1 or 2 in a million people.
In December, Briana received a bone marrow transplant, but it unfortunately failed.
She's supposed to receive a second bone marrow transplant sometime this month. To keep her alive and healthy, her family and supporters are looking for donations of white blood cells.
And in the meantime, because her immune system is so compromised, she's living in isolation at the Texas Children's Medical Center.
But that hasn't stopped her from following her passion: Yoga.
Despite the fact that she's in the hospital, Briana manages to post herself in a yoga pose every day on her Instagram.
Here she is, in isolation, doing the Samakonasana pose.
She does a pose a day, no matter the challenges.
Many perfectly healthy people can't even do this (which is apparently called the Utthita Hasta Padangusthasana).
This one, too (it's called Hanumanasana).
"The progress is what keeps me engaged," she explained. "Keeping up with challenges and a yoga community in instagram holds me accountable and pushes me to keep trying everyday. There's never any failure, only success in a journey with yoga."
