I understand how difficult this is for you & your son. My son was dx at 15, so we went through a lot of the same things you have.
It's a terrible feeling when you your doctor says "I'm sorry to inform you, but it looks like your son does in fact have CF". I'll never erase those words from my mind. BUT after the shock/pain/fear subsided, and I found this amazing site, I was glad for an answer to the years of questions I'd had about his health.
You will find much support and education here. Most importantly, you will likely find hope here. I know I did, and it's been invaluable to me over the years. Jordan's disease was not as severe as others here when I first joined, but he has progressed some. By reading everyone's experiences here, I was more prepared for things as they came. A month or so ago, Jordan experienced coughing up blood for the first time. <img src="i/expressions/face-icon-small-sad.gif" border="0"> It was frightening, but I knew that the amount of blood he coughed up was nothing to completely panic over, because of this site.
If you ever need to talk, just send me a PM. I'll be happy to help in any way I can. (((((hugs)))))
