I probably have a slightly different perspective.... I do agree that treatments are essential to staying healthy.. no if, ands. or buts. However, I also think that mental health is just as important.. That is a ton of treatments she is on, if you are doing two hours in the am, and then two hours in the evening.. That is a lot. I only do one hour in the am and one hour before bed and sometimes it doesn't take that long...and I still hate it and have grown to resent the fact that I am demanded to spend so much of my time on treatments. I feel as if my time is stolen from me.
I wonder if their is a way to make things better for her, Maybe it is just where I am at in my life... (I am 33 dx at29) but quality of life is more important to me then just about anything..and if you are miserable all the time, it doesn't give you much insentive to care about being healthy much less anything else..
Is their a way you can help her with some of those treatments.. Like doing the nighttime feed for her, or maybe instead of doing nebulized albuteral if you even use it, try a hand held inhaled one, anything to cut down time....Maybe she can try using the computer and networking on IM or something to make the time pass. How about giving her insentive to do time on the vest.. Like for each day she does all her treatments, she gets some sort of reward, extra privlidges etc.
I don't think telling a teenager that she has to do this or she will get sick is enough.. I bet she probably doesn't care if she gets sick since she is miserable anyway... Shamefully I can feel the same way sometimes....If you have another child that has CF and doesn't need to do that many treatments, I am sure in your daughters heart she is happy for the other child, but that has to make her feel aweful and question what she did wrong or did to deserve being sicker... Maybe she just doesn't understand.. the way sickness is.... (or maybe I am projecting my own feelings ha ha) I would reassure her, and help her find her own way in life...
My point is in an ideal world ppl would do what was the best for them.. but sometimes they need a little help to get through hard situations, and sometimes that help is not telling the other person what to do but rather helping them to do it, being there with them, and making it easier to do. I know ppl whos spouses, parents or partners have helped by playing games with them, or sometimes actually hooking them up to the feeding tube or IVs at night so they could sleep etc.
I hope I made some sense... I am sure that with a little love and persistance your daughter will be back on track...
Good Luck,
Jennifer
