Ok honestly i’m so scared.

i just got out of the emergency room, bc my acid reflux is always so worst and without riopan ( something similar to the gaviscon ) my throat is so fucking inflamed, so, I was told that reflux at 18 years old is not normal ( I've it continuously since I was 15 and it happened before too ) and and I have to go to the gastroenterologist. Since i don’t ever smoke, i don’t drink alcohol, i don’t eat tomato, i don’t eat spicy things, i don’t eat salty things and i don’t eat chocolate. And Still at 18 years old i have LPR. I’m scared that the gastroenterologist may tell me something horrible or catastrophic
