Reflux Esophagitis, Gastritis, Colitis, Hemrroids, and Hiatal Hernia

I have been dealing with these for a year now, my doctors are unable to find a cause for what is going. I have stopped 95% of food forcing myself to eat at least once a day with bone broth, tea, coffee, water, and juice. With meals I have to force myself to eat due to the pain that comes shortly after eating, and when I do eat what I do eat causes the worse diarrhea. Sometimes I am constipated others I am ready to set up camp in the bathroom as im not sure my next one ill make it to the bathroom. I wake up in pain and tired when talking to my doctors they say "I'm too healthy" for any type of supplemental nutrition. Ive had a colonoscopy, endoscopy, several CT scans, a barium swallow, and a biopsy which was normal. My autoimmune test have come back normal but with a high ESR, and protein in my urine. Allergy testing has come back to not being allergic to anything. My last resort is to complete stop eating and wait for someone to give me any type of supplementation and wait for my exploratory surgery March 9. I am a mother of 2 too exhausted and in pain to be there for my children.
At this point almost all options have been taken to see what is going on with not a diagnosis in sight, I come to this forum for help and suggestions.

Yes but it’s the only way my doctor will give any type of supplemental nutrition despite the intense pain with foods and the dehydration they say there’s nothing they can do

GERD: Try to sleep on your left side with your head above your stomach, it will reduce the acid reflux. It is a terrible thing to feel unwell with nobody understanding what you go through every day. I was diagnosed with GERD. There are food, drinks & drugs that trigger the reflux,you just have to find out that yourself. Now it is sore throat with a lump in my throat. Every day new symptoms comes up. It is not an incurable disease. We will get over it soon.
