My name is Grae and I am a 20 year old Cystic Fibrosis patient. Cystic Fibrosis is a life threatening genetic disease that affects the lungs, sinuses, digestive tract, and reproductive system. It is a rare genetic disease that only around 30,000 people in the US live with. This blog is basically everything you could ever want to know (and some stuff you definitely aren't asking for, but you're gonna get anyways) about living with a chronic illness.
