CF is a violent curse, not a blessing. I wouldn't wish it on a worst enemy. Whatever peripheral side effects it might correlate with that are okay are completely negligible in comparison to its horrendously debilitating nature. Aside from maybe Alzheimer's disease or infant leukemia, it's about the best proof there is that no benevolent "masters" are floating around the universe.
Taking it one day at a time is a healthy attitude, though. You <i>will</i> get scared, but not necessarily all the time, so just enjoy whatever you have for as long as you desire to live (and, more importantly, keep an eye out for things that would make it all worth it, like romance).
