Confusing stomach troubles

[Sad__Stomach]

Hello,

I am 23F and have been dealing with a rather strange issue so I wanted to see if anyone else had experienced it. For many months now, my stomach has been producing way too much gas. It's constant belching to reduce the gas and it keeps going all day. I've been to the doctors, at first they found a fecal impaction and thought that was the cause so I was put on various stool softeners and laxatives to help that, most of which made me very exhausted. After that, since the problem persisted, they put me on omeprazole for three months, thinking that the damage to my esophagus needed time to repair to end the issue. Right now, however, towards the end of my treatment and nearing my next appointment, I feel no better. On the omeprazole, the symptom is controlled, but off the omeprazole, my stomach becomes extremely bloated, I am in constant discomfort, and there is even a lot of reflux depending on what I eat. I have also been put on a high fiber diet for this entire duration, and have removed anything that inflames my stomach from my diet. However, I am still about the same in terms of the way I feel, and I am getting quite frustrated. It is difficult to exercise and feel energetic when I constantly feel lousy. I honestly don't know what to do anymore and it feels like no one seems to know what is wrong with me, and the next step in treatment is going to be an endoscopy, which I really don't think will help anything. Has anyone experienced anything like this before?

Thank you so much.
