Hello Erica and welcome to HW! My condolences go out to you for your cousin, Brandi.
Not really sure how others deal with CF, but as for me and my youngest son (who has CF) and our family, we take "one day at a time".
How wonderful that you are raising money in honor of Brandi towards research on CF! Kudos to you and congrats on being Mrs. Gilbert America 2007!
