hi there, i am really sorry to hear about your loss....i am 18 and have CF and i know that for me it is my friends and family that keep me strong and make my life so much easier! i have also lost several friends to CF and its an extremely hard thing to come to terms with. there are various websites explaining the disease including www.cftrust.org.uk and there are some useful (but very complex!) articles on www.cysticfibrosismedicine.com if you want to read the sciencey stuff.....email me at tinypoppet@hotmail.com if you want to talk, or want any more info on it. take care, my thoughts are with you.
