Kind of looking for advice but also just want to rant.

I'm so freaking sick of it. Literally and figuratively. No matter WHAT I eat, how I sit or lay down, the amount of time I wait in between eating and laying down and stuff, I always have bouts, and it makes me feel like I'm suffocating. I've already had a an upper gi endoscopy and lower gi colonoscopy last year and it came back normal with slight signs of prolonged acid reflux, but no matter what medications I take, the symptoms don't go away, and I've tried changing my diet, I have, but it just doesn't freaking work, and I'm at my wit's end. I'm so sick of it, and it's not like I can see my gastroenterologist because he switched practices because the hospital he worked for shut down and it's going to take a while before I can see one again and I go to college at the end of next month.
