I feel like I can't take a deep breath. Like, I'll try to, but my lungs aren't satisfied. Then, I try to yawn, and I feel better until the yawn is over. I've had really bad gas for almost a week. Not like passing a lot of gas, but like I need to burp but I can't as often as I should. When I do, I feel better, like it released a lot of pressure. The gas is stopping me from eating and breathing properly. I feel bloated even though I haven't eaten, and I feel like I can't take a full breath. As a result of this, I have trouble sleeping. Gas x isn't working. I scheduled a doctor's appointment and went to the ER. They said that I'm feeling this way because I'm about to get some other type of illness. I feel full when I have't eaten. I'm having a hard time breathing. I feel like I'm not getting enough oxygen, so I try to take a deep breath, but it isn't working, so I try to yawn to compensate for that. I'm burping a lot, and I feel relief when I burp. My stomach feels bloated. I have loss of appetite because I feel too full to eat. My bowls are regular, but I don't know what's wrong. Some people said that it was anxiety, but I don't feel anxious. What's wrong with me?
