Hey everybody, I'm Caitlin, i'm 16 and I have CF. I just had a couple of questions for other people with cf to see if this is normal or not. Lately I've been really tired and have felt just worn out for no reason and I'm sleeping alot longer than normal. So I wanted to see if this is a bad sign or not, if maybe i'm not getting enough oxygen in my sleep or my lungs aren't doing good. I've also been coughing up alot of blood, but it feels like its just coming from my throat and its coming up really easily, when I feel I have some gunk down in my chest and try to cough deep to get it up, I can't and its just like blood. So please help me figure out if this is kind of normal and will just go away soon, or if its alot worse than that. Thank you!
