"I have never in my life received such a wonderful gift. Not just from a friend, but from another CFer. Because of Mark (Wing for CF Inc), I'm now able to pay for my medicine I need and my debt I owe. I don't know how else to thank you! You are an amazing human being and an amazing fighter! Stay strong fibro and thank you so very much! Tears of joy." ~ Renee Durak, CFer
