I am 20 years old and have what you might call a severe case of CF. I have always been very sick with my CF, the longest I have ever been outside the hospital was 5 months, my hospital stays are always 2-3 weeks, and getting more frequent. now I seem to be in ahout ever 6 or 7 weeks. I have never been able to hide my disease, and I find when I tell people about it, their reaction is a good beromiter to how good a friend they will be. those who freak out, will turn and hide the first time you get really sick, but those who are suportive, and see you for you rather than your disease will be suportive no matter what. CF is a part of your life and there is nothing you can do about it. it is a part of you, it is progressive, it will get worse, and it is best that your friends know about it now while you are still doing well. this isn't to say that I advirtise that I have CF, but I don't hide it, and when things come up they come up. I recently had to drop out of college because I was spending to much time in the hospital I couln't pass my classes. my teachers, and the other students all knew what was going on, they were all suportive, and told me that if I ever could come back I would be welcome. I had a bio major, I know all about studying genetics in school, I practicly tought the unit on CF.
I guess the point is, tell your firends, if they arn't suportive of it, find better friends.
