Gall bladder disease? Am totally drained

I have had Ibs type symptoms since January this year, which have not gone away, with my tummy being constantly bloated, I look pregnant and is constantly tender. Then in February I started getting problems which I thought was from a past ulcer problem, saw the gp and he confirmed took medicine and since have developed pain in my right upper abdomen which goes round to my upper back and into my right shoulder, this is happening most of the time, and am still getting lots of acid/gas. I am feeling totally drained and over the last week or so my appetite has gone. I am still working 9 to 5 but struggling to keep going. I have had a scan, which showed no gall stones, after speaking to various people they think I might have fatty liver disease, the pain does get worse when eating anything remotely fatty or greasy, although the pain is still with me most of the time. Does anyone else feel like this? I am due to see my doctor again to get the full results in a weeks time. Am feeling so down with this as it seems to have taken over my what was once active life and sapped all of my energy. Any comments or help would be welcomed.
