WHAT IS WRONG WITH ME?!?

m currently 21 years old, over all have been healthy my whole life but i seem to have a problem no one can figure out. Since November of 2008 i have a horrible digestive problem. EVERY time i consume food or liquid i belch uncontrollably. My stool is normal as is my "farting". Ive been to several doctors for it and they some how try to convince me im crazy and its just acid reflux. Ive takin nexium and prilosec for some time and never say any results from it. Ive gotten an Upper GI and it came back "normal" as well as an endoscopy and the doctors comment was my stomach looked a little red but also checked out to be "normal. Ive also had my surrounding organs sonogramed to see if they are "expelling gas into my stomach". NEGATIVE everything checks out fine. I feel the gas build up in my stomach almost instantly and can burp consecutively, they are also very "deep". Any help or advice will be greatly appreciated i seem to be out of options. thank you very much
