Hay Mackenzie!!! I love 7th heaven!!! I am not typin this message to tell you all about how your my biggest fan!! I am typing it to say thanks!!! I think it is so sweet how you are a supporter of the CF foundation. Because my best friend is 13 and she has it! Her name is Amber. And i am also a supporter of the CF foundation!! During the month of June we held a CF walk for the CF foundation we raised about 13 thousand dollars. It was a 8 mile walk. We had a silent aution at the walk also!!! I hope that one day that the Cytis Fibrosis (CF) Foundation will find a cure!! That way all the people who have it will no longer have to suffer from it!!! When i watch my Best Friend do her VEST and her Breathing Machine i feel so bad for her!! I have your step sister in my prayers!!! And please never give up hope for the CF foundation!!! And for that fact that you are a CF sponser you are my HERO and my BIGGEST FAN!!! THANK YOU!!! and please write back!!! I'll never loose faith!!!
