Briana Donis is battling a life-threatening disease.
Aged 19, the teenager from Houston, Texas suffers from a rare condition called aplastic anemia, which occurs when the body stops producing new blood cells.
The health condition is dangerous and can leave sufferers feeling extremely fatigued, while also making them increasingly likely to contract infections or experience uncontrolled bleeding.
Back in December, Donis underwent a bone marrow transplant. Sadly, it failed.
Now, the 19-year-old is enduring chemotherapy to prepare her for a second bone marrow transplant. But the treatment has taken its toll on her immune system and has wiped out all of the white blood cells from her body.
As a result, she is now living in isolation at Texas Children’s Medical Center.
