Apparently there is “nothing wrong with me”

According to the test results from the stomach emptying test, I have “nothing wrong with me” and I am so fucking discouraged. I know people say I should be grateful, but there IS CLEARLY SOMETHING WRONG. I’ve lost close to 50lbs in a month, and I can’t even keep a sip of water down at this point. I went to the ER today for fluids, and not only did they not give me fluids, they also gave me Zophran and that’s IT (it literally does nothing). I don’t know what to do…
