Holly,
You sound pretty frustrated and well, I'd rather you be frustrated than not care at all. I'm sure you're hurting and maybe even scared? As a parent of a teenager with CF, I must tell you, sometimes I don't understand it when he slacks with his insulin or after 13 years, sometimes forgets to take his enzymes. But that's what being a mom is about...we worry. We love our babies and we want to keep them with us...for as long as possible.
Austin gets on me because I nag at him. Too darn bad! LOL If I didn't nag, he would most likely forget to eat!
Your parents just want you to take care of yourself, because if you don't, you won't be well enough to go out and play with your friends or go places. I try to put myself in my son's shoes and I get pretty scared. Maybe you might try to put yourself in your parent?s shoes, and see just how scared they may be? I have no idea what your home life is like, but here, we love each other deeply enough to worry about one another and go out of our way to talk about our feelings...tell your parents how you feel...OK?
