Hey everyone.. my name is Jessica and my best friend has CF... Hes 19 and the doctors told him that he had a 50/50 Chance of living to be 20. Ive read some of the other peoples ages and diagnoses's and i am holding on to the hope that he will make it to be 20. I was wondering if there is anything whatsoever that i can do to help him and what are the actual chances he will live?
