Bloating never goes away

I don’t know what’s wrong with my stomach. I got a SIBO test (methane) which apparently came back negative, an abdominal xray and a thyroid hormone check. My stomach is bloated as soon as I eat anything, and gets worse throughout the day as I eat more. It’s never flat, not even in the mornings, it’s still bloated from the day before. Although gluten seems to make my issues worse, I was gluten free for 2 months and was still having bloating and gas after eating literally anything. There was a few days where I wasn’t having dairy either and my stomach was still the same. Im so frustrated, I’ve tried a million different supplements that say they make bloating go away. Nothing helps. The only thing that worked for 1 day was Inno Cleanse. Do I just have digestion issues? My stomach is making loud noises as I type this lol. So tired of dealing with all this bs
