T's mom, I don't have CF but I did want to post a response to your question-in general. Sometimes I wished my parents would ask me questions and since my mom and i became closer after I moved out at 16, she did start to get more involved in my life. after I moved out, we had mother daughter days where we would window shop and go out to lunch, it was just the two of us all day on a sat. or sunday afternoon (or whatever day I had off work, she was able to rearrange her schedule)about once a month. That was when I would be able to share with her what was going on in my life, and instead of her giving me feedback and suggestions, or scolding (unless I requested for her to share her opinion, which I started doing after a while) she would just listen, or say something like, "I remember when something like that happened to me" and she would share her story so we had something to relate about, even if it occured 30 years ago. It was really nice that we were finally building a relationship where she was more like my friend than my mother (and especially remarkable if you had lived in my house and seen the way we treated eachother, my poor dad never knew what to do about it). I just wished the door would have opened sooner.
I am still young (21), not sure how old your daughter is, but you could start with making a fav. treat of hers and asking her to join you outisde after dinner, or take a walk one evening after dinner and just ask her how school is going, how her friends are and if they've done any really fun things together lately. If you two dont usually talk about "personal" stuff very often, you are probably going to blow her out of the water, and maybe scare her if you start asking about her health and her thoughts of the future right off. Some people are very private about that kind of stuff (my husband for example, refuses to disclose his CF...) so a slow gradual approach is best. I didn't have health problems and the emotinal side of those problems to talk to my mom about, but something I wish I would have been able to talk to my mom about, but wasn't was me being sexually active. I am not saying that your daughter is, I hope I don't leave the wrong impression here, but it is something I wanted to talk to my mom about, the emotions and feelings associated with it, making sure I was doing the right thing... but I was fearful of bringing it up because I though she'd freak out and think she didn't do a good job raising me and that I might be in big trouble...
I guess my point is that if you ask, and she doesn't open up right away, give it time, talk to her every so often about it until she opens up to you-because she will.
I am not sure if that helped at all, but maybe some CFers will see and post in response. I am sure they can give you some more specific guidance regarding the health/emotional concerns.
