I was diagnosed the day before my 14th b-day. I had been getting a lot of stomach aches and I was coughing up blood...The family Dr. I was seeing said I was doing it all for attention...I dont know how anyone can cough up blood for attention but, anyhow, I finally went to the ER and the doc ordered the sweat test...Thats when I found out...Happy b-day, huh? And for the family doctor, he got out of town when he heard that he had been such an idiot!!!
