Misdiagnosis?

So my family doctor diagnosed my mom with gastric reflux several years ago. When she was pregnant with my younger brother, she found out she had CF. Now he's telling me I have gastric reflux. He won't schedule a sweat test, maybe I'm just overreacting? Can gastric reflux be in any way related to CF? Or maybe mistaken for CF? Sorry I've just been sick for so long and I'm tired of going back and forth and getting different diagnosises, I want to know for sure what's wrong with me so that I can get treatment that will actually help. I'm just tired.
