I noticed in the adults section that there seemed to be a problem with replying to your post. I will try and see if it works.
I rarely come to the teen section because I have always felt that it is for teens to reach out to one another and that they may not want a MOM to nose in.
As a mom though, I feel your struggles with all of this. It is a an unfair hand your and all CF'ers have been dealt. Your feelings of just wanting things to be "normal" if even for just one single day are normal feelings. I know there were times that I wished for my two girls that they could have a "normal" day like every other kid, where they didn't have to worry about taking meds and doing treatments. For the longest time I never questioned why this has happened but my oldest has. We are not extremely religous people but we do believe and believe in the power of prayer. It is what has helped at least me to cope with all that CF life has put us through. I do go to our priest and ask for his guidance and input on how I/we feel. At one time the question was put as to why God has allowed this to happen, why me, what did I do? What I see is that God has not allowed this to happen but that this suffering is evil at work and the good things are God fighting to make them better. Sometimes it is hard to see the good things but you have to look and you will see them.
On a more clinical thought, do you see anyone for your depression? I highly recommend seeing a professional. If you are not on anti-depressants maybe you need some but only a psychiatrist can prescribe and tell you if you will benefit from them or not.
As for your treatments. You hate sitting still for so long. Who says you have to sit still? While you are nebulizing, you can be on the computer, (here's mom talking) clean your room, exercise. Exercise... If you have a stationary bike or a trainer for your bike, you can pedal away while nebulizing. It's a good workout for your lungs and may help you breathe deeper thus getting the medication deeper. You don't have to go fast but you are moving.How about a Wii? You can play all sorts of games that require you to move. As for CPT, it depends on what you do. If you do the vest, like so many do today, I have no idea because I don't really know how it works but I would think you could Wii while vesting. If you use a mechanical percussor or manual percussion then you just have to sit/lay still for 30 min. and get it done. Flutter or pep? I think you could bike and flutter/pep at the same time, you just would have to pedal slowly and steadily.
I am sorry you are having such a difficult time. What do your parents say about your struggles? Do they know how you feel? How about your CF docs? Many young people go through a time like this, feeling what you are feeling whether it's CF, Diabetes or some other lifelong disease so you are not alone.
