Thank you all for your suggestions and support. After spending the last 3 days obsessively researching CF, I am comforted and more scared at the same time. In regards to my sister, I am comforted. Over the last six years she has gone from being a healthy, active mother to someone who rarely gets out of bed except to attend doctor's appointments-wondering what's wrong with her and acting like she's expecting to die soon. I am hopeful that the correct diagnosis and correct treatments will lead to a dramatic improvement.
I am, however, scared for myself. I was always the "sickly" one of the family growing up, and now knowing that her diagnosis is a genetic one I am pretty worried. I decided right away that I wanted the sweat test done as well as the genetic testing, and planned to have one of the docs I work with order it (thinking I could have results back in a day and ease my mind). After calling around to the largest hospital in my state, I was told that the sweat test is "out of date and not done anymore." I've researched enough to know that this is absolutely incorrect, but that's what you get when you live in Wyoming. I guess I will just have to wait until my sister's genetic testing comes back and then get tested for her mutations, as I can't afford the full genetic analysis.
Thank you so much to everyone on this forum-I have spent the whole day reading various threads.
