Here is my opinion from a CFer who is 26 years old and has had a little insight into this exact issue. I was exactly like your daughter was when I was 14 years old. I didn't want to do any of my treatments, I didn't want to listen to my doctors in any way, I hated to be nagged, I wanted to be left alone, I wanted to be normal and looking back on it I made my families life (especially my parents lives) a living hell just being a teenager, not to mention a teenager with CF. If I could do things all over again I would say I wish my parents had nagged me more. I wish my parents would have grounded me every time I didn't do a treatment or every time I drank a Pepsi (I was diagnosed with cystic fibrosis related diabetes when I was 13 and I still have a soda addiction) I wish my parents would have duct tapped me to a chair, strapped that vest on me and sat on me kicking and screaming until all of my respiratory therapy was complete for a day and then some. Honestly, it would have saved me years and years of my life. I did not comply with what my parents and my doctors told me to do and I have paid a heavy heavy price for it. My life will be shorter because of my stubbornness. I began to deteriorate by 18, was on permanent oxygen by 22, was on the double lung transplant list 3 months after going on oxygen, was forced to with drawl from college and go on disability permanently by 23 and was in the ICU and on life support by 24. By the grace of God and my wonderful donor I received a new set of lungs with literally less than a week less to live and there is no doubt in my mind that none of that would have happened if I had been more compliant and listened to what my doctors and parents had to say. I have literally been to hell and back dealing with this disease and I still continue to struggle, even after getting new lungs. I don't mean to tell all of this to scare you but I would hate to have your daughter go through the same thing that I have gone through. I still struggle with compliance to this day and it effects my family, my friends, my boyfriend and most of all me. It is not your responsibility to be her friend, it is your responsibility to be her parent and unfortunately when you have a child with CF you have to be more strict than the average parent. It's your responsibility to teach her how to live a happy productive life with this disease and a huge part of that is for her to learn how to take care of herself. I honestly feel it is my responsibility as a delinquent CFer to share my experience with other CFers and especially other parents so that they can learn from my mistakes. If nothing else I want my mistakes to benefit others. If you or your daughter ever want to talk about anything please please don't hesitate to PM me and we can exchange e-mails or maybe even phone numbers. I would be more than happy to chat with either of you as much or as little as you want or need. We CFers and CF family members need to stick together!! Sending you lots of positive thoughts and love!!!
