I have a friend that got engaged recently, he has cf. Evidentally her mom has problems letting go of her baby and tries to find cf as an excuse....Then my own mother in law had problems with me...her excuses (as valid as they maybe) were how can my husband support me, i have an expensive illness, I will be sick alot can he handle the fact he can not "fix" me (my husband likes to fix things), etc. I think people have a problem, or a stigma thinking "why date or marry a sick person" as if a healthy person is taking pity upon a sick person...or that sick person cant love, or take care of the other like they should (such as getting a job or taking care of the house or kids).... Its also just happens to be those same people with the thinking "why be with a sick person" who get cancer or a loved one gets cancer, and its like does your love for them change? NO! But we are lucky/blessed to find those who are not just willing but who want to be with us no matter what.
Now to the original topic. Your son is very fortunate to only be having problems now. I saw just talk to him, try not to nag, thats the important thing, dont nag...Just let him know you love him and would like to see him take better care of his self. make points that you need him, his girlfriend needs him for a long time. Does he live at home? If not maybe take him grocery shopping to encourage eating, or if he lives at home by him anything he is craving at the time. It might be a pain (i know it is) but sometimes you have to do anything you can to keep weight on. Key words are "do not nag" it can only make things worse.
How do I live being an adult with cf? Just like anyone else but with more maintance. Sure I may slack off but I am getting better at not doing so. Slacking off is a phase all of us go through. I think it starts any where from 12 and lasts any where to late teens early 20s...some last the whole time, some only a short time. Its part of us growing and learning and wanting to do stuff like everyone else. I just live like I should. I have fun, I am married, I love to garden I love hanging out with my friends. I just have to do alot of extra stuff to be able to have fun...such as keeping up with meds and treatments so I feel well enough to do the fun stuff.
