If the testing does confirm I have cystic fibrosis, would I have a valid case for delaying treatment and diagnosis for so long?

For the last 5 years, I was having frequent sinus infections, upper respiratory infections, stomach issues, and a lot of other symptoms. I literally was on antibiotics almost every other month. Every time I would go in, I would be told that I was a mom, I should be tired and it's normal to be sick all the time with kids that everything I had was anxiety. I was frequently sick and finally had enough when my doctor told be "have I ever thought about moving to another state, because I maybe I have bad allergies". I told her this isn't normal and I don't know anyone who is this sick all the time. She chuckled at me but decided to send me to a pulmonologist to put my mind at ease. Pulmonologist ordered a CT scan which showed I had bronchiectasis which is kind of rare, did some further testing and now there is a possibility it is cystic fibrosis. I'm 35 years old as well as immunodeficiency which would mean that I've had this condition for my entire life. They kept telling me I was fine that it's just anxiety. Countless times, I went home crying to my husband telling him that they basically dismiss me and tell me everything was because I was a mom and run down. I knew something wasn't right and they wouldn't listen to me.
