question: I keep feeling extremely short of breath, it feels like my lungs arent filling up enough or that their is restricted chest space. I have also been exhausted for months,  getting headaches and a pain behind my left eye and chronic stomach pains. I have become very windy and am almost constantly burping and have been suffering with heartburn. Things are getting worse everyday and I feel like this 70% of the time now, I also feel worse when I lye down in bed and I have to keep sitting up to burp. This is making me very anxious all the time and I now think im suffering from anxiety attacks also
