aw, u don't sound rude, sweetie.
Sorry this has been a tough year for you. We all have the scars from years of needles and IV's too. Maybe we could all get together and see who has the most, and that person gets a prize! Just kidding.
My advice to you, which probably sounds boring, is try very hard to do all your therapies and take your medicine. Also, I don't know if you take enzymes, but when I was little I always forgot my enzymes when I ate. Sometimes, I even just wouldn't take them. Now, I have some stomch trouble because of that. So really try to remember your enzymes.
Also, it would be good for you to get involved in some type of sport or outdoor activity that you like. That will keep your lungs clean and your body moving.
I think the hardest part of being an adult with CF is that when you have a job, and you get sick, you miss so much work. And your boss doesn't like it. And, now that I am 23 and married, I am thinking about having some kids. That will be very hard too, taking care of them and my health. Also when I'm in the hospital I miss my house, and my dogs and my bed, but you know how that feels!!
You are very young, and you have a long, fun life ahead of you!
