Non functioning gallbladder and motility issues

Morning all, wishing you a good day.
Sorry this post is kid of long but I work toward an understanding.
I post on several forums here as I have lots going on and trying to figure it all out.
But I am really struggling with gut health...or lack of it.
I am just always miserably sick. And horribly tired.
I have have stomach motility studies that show my stomach empties very slowly which explains a lot about why my plate stares me down. I end up eating like a three year old, a bite or two here a bite or two there.
Not a great way to eat nutritionally, as it makes it harder to see if I am eating well.
But that isn’t all, my GI health is not good at all. Motility overall just seems non existent at times.
I must use senokot s, or lactulose, or restoralax. The stool isn’t hard like constipation it is more like things just don’t function too well or often, like it’s asleep or something.
Also the gallbladder doesn’t function period. It is not diseased, no stones or anything, just does not function, as per a HIDA Scan. So they want to remove it....even though they make it clear it might not fix anything.
When “everything just stops”, stomach, bowel, it seems it aggravates this non-functioning gallbladder and I have acute pain and terrible nausea. I can’t eat period. If it goes on long enough and the laxatives don’t force movement of my entire GI tract my biliary system gets terribly inflamed. Talk about sick....I turn green grey and the dark circles under my eyes...well just a real
attractive gal. Well then the inflammation takes over, as the epithelial cells or lining of the gut gets inflamed.
My rheumatologist has mentioned irritable bowel before but it seems that irritable bowel although it has lots of known symptoms, there is not about getting a true diagnosis.
The thing is once I can get things moving I am not all better, but much, much better.
Does what I am describing sound like irritable bowel? Is there a way to get a definite diagnosis?
Can it be fixed or at least controlled?
Thanks so much for your patience, tuffymason.
