Carly,
I sympathize with you as I was in this same exact situation about 7 years ago. I was diagnosed with cepacia as well and was scared to death. But now I'm HEALTHIER than I was back then and it hasn't caused me any problems. In order to keep it under control it is important that you do what your doctor says and it shouldn't be a problem (I have become 100% compliant since I was diagnosed with cepacia and you wouldn't even know I had it). This is unfortunately just another hurdle that CFers have to face and as hard as it is carly, it is important not to get down about it because that will only make you feel worse. PM me if you have any questions <3 we're here for you!!!
