Have you considered that maybe your parents are terrified of your CF. My daughter is almost 11 and she is in diagnostic limbo regarding her diagnosis of CF. Just the possibility that she has CF terrifies me. I would definately sacrifice my daughter's opinion of me if I fealt that it was the only way to get her to do her treatments and then have a chance to out live me. I often dream that I have donated my lungs to my daughter who is now in my dream living free of lung disease and I am watching down on her from heaven. It is crazy what a mom will do for her daughter. I would do anything. I am fortunate that so far our relationship has gotten closer as she has begun many CF treatments. Tonight she went on this website for the first time and I hope she doesn't get depressed about the disease especially since we don't know for sure if she has it. However, I also hope she sees the consequences of not doing treatments and continues to be proactive with her care. Try to start a serious talk with your parents about how they feel about CF. Ask for the truth without the sugar coating. You may be surprised about what you hear (fear versus anger). I wish you the best.
