Jake,
First of all, I am so happy that you are doing so good. My fiancee David is 21 and his lung functions are at the same level as yours. As far as telling people goes, don't be ashamed! Don't be embarrassed either. It is part of who you are, and always will be, so just take it all in. When you find the right person, and they find you, it won't be an issue. I know it isn't with me. But you should tell people, especially those you are close to. I know when David told me in about 9th grade, I was really interested. But I also did the stupid thing and jumped on the internet to learn about it. Bad idea. If you are dating someone, I just think it is probably a good idea to tell them. Especially since you are doing so good, that is inspirational. You never want to give people the idea that it is something to be ashamed of. But at the same time, if it makes you uncomfortable, don't tell people unless they need to know, ya know? I don't know if this is helping you at all, I hope so. When I found out that Dave had it, I cried and cried and didn't know what to think, but nothing negative ever came across my mind. It actually made me more interested in him, and now we are both really active about it. But at the same time, it is not who he is, it is just a part of him, you know? Sometimes people let it take over there lives, or other family members can get obsessed and forget that cystic fibrosis isn't everything about the person. And that I think can really hurt people. It hurts David when the first thing someone who knows he has it says, 'how are you feeling?' or 'how are your lungs' and the big 'have you been doing your treatments?'. Some people care, some people smother. I think the end all decision of when to tell people is up to you. It depends on your comfort level. As for me, it brought David and I closer together. Honesty is good. I hope this helped you. I am glad you are doing well.
