1. I will echo many others. It’s amazing how far medicines and treatments have come.
2. It’s kinda incredible You made it this far. Probably due to you having a mild case, but honestly many kids who go undetected suffer a far worse fate.
3. If you have no lung issues that explains number 2. It’s really is one of the hardest aspects of those that have CF. But even then like stated in 1, the last 5 or so years have changed this immensely with meds.

I would recommend joining some online CF
communities! You will be great! There a lot of people out there that have family members with CF and will be supportive. At the same time you will have a chance to educate others on what CF is!
You will do great! Keep your head up!
