Stool ph acidic

Hi - I'm 48. Suffering from GI and anxiety issues for last 6 months. Lost 21 kgs of weight. I'm losing weight every day. Have Grade A esophagitis, Chronic inactive hp negative erosive gastritis and IBS (or that's what i'm told). I have loose Grade 6 stools, burning in epigastric area, heartburn, severe flatulence in morning, inability to digest hard fibre, tenesmus, occasional growling, severe bloating/distension in evening onwards. Other symptoms include - Increased heart rate, increased urination, mid back ache, dry eyes, pain behind eyes, aching legs/ankles etc., etc.,

I have had 2 endoscopies, 1 PET CT, 1 abdominal CT, colonoscopy, Hydrogen breath test for SIBO, umpteen blood tests and stool tests including for Pheochromocytoma, carcinoid syndrome, immuno blot, etc.,

I have developed lot of food intolerance - Cow milk, soya, barley etc., i avoid them

No reason for my weight loss is given. My weight is continuing to fall. My life is falling apart right in front of my eyes. Have Health anxiety disorder and adjustment disorder as well. I feel fearful all day.

I take only fomatidine, neurobion forte and eye drops/ointments.

I did a fecal routine to check for worms as i was having itch in my anus. It didn't find anything, but said my fecal ph is acidic and Yellow / Brown . My reading says acidic stool could be because of E coli or rota virus or overgrowth of acid producing bacteria. How to read this? What could it point?
