I bet you have got some scared feelings going on even though you seem pretty calm about all of this. Don't worry you are not alone. I am 47 and was just diagnosed two years ago. It wasn't that I didn't have symptoms, but I just kept getting misdiagnosed. I was told I had astma and copd. Fortunately, the meds used were some of what I need for cf, but they were smaller doses of what I take now.I can tell you I am doing better now than I was two years ago when I was in the hospital AGAIN with pneumonia. I am thankful I didn't find out until I was grown because my parents would have "put me in a bubble" not letting me do anything, since they are overprotective. I got to enjoy my life and do everything I wanted. Now, I realize sometimes I have to slow down and maybe be a little more cautious. I can still enjoy life and make sure I do every day. Don't think just because you are "old" by cf standards it doesn't mean that you won't be able to be around and doing good for a long time. Take care of yourself and you can do it.
