C diff positive, symptoms don't match

First the question and then you can read the background if you so choose:

Has anyone had/is is possible to have a chronic infection with c diff and present with mild, "controllable" diarrhea/chronic loose stools for like three years? This symptom is accompanied by more bothersome symptoms of pain, extreme bloating, unpassable trapped gas and the feeling of fullness/need to belch.

I am a 40 year old woman and have had what I called IBS since I was about 21, though there were long spaces between flares and I could manage by eating easy to digest foods for a awhile and be fine, but three years ago after going through a catastrophic life event and the accompanying stress it became severe and ongoing, getting worse and worse until the good days are few and far between.

I finally broke down and went to a gastro doctor. She did a stool test (twice) and both were positive for c diff. In the meantime (though delays with the incompetent office) she prescribed rifaxamin for sibo even though the test machine was broken so I wasn't actually tested, but symptoms matched. Once the second stool test came back positive (the first she though was a mistake) I was put on vancomycin. I just finished that 2 days ago and feel no different.

I was scheduled for a egd + colonoscopy for the same time, but they were so scared of the c diff, (which I have read a sizable portion of the population has and is asymptomatic anyway,) that they postponed the colonoscopy. The egd was normal. They did biopsies for celiac, but not h pylori. After suggesting I might have h pylori, due to the chronic need to belch, they did not test stool or stomach lining.

I had my iron levels tested and am anemic.

Thanks for reading.
