Struggling with the after effects of intestinal surgery for crohns

I've struggled with this disease since I was very young, I can't remember a time before my symptoms, but I was mistreated, disbelieved, and misdiagnosed until I was in my mid 20s. I had a bowel resection and roughly 12 inches of necrotic bowel removed, including the removal of my iliocecal valve. Since then I've been on Remicaide, Infliximab, Entyvio, Humira, and Cimzya, and over the decade have continued having symptoms but during colonoscopies have been unable to find active disease. Still, I've struggled with chronic fatigue, enteropathic spondylitis, Gerd, insomnia, Hidradenitis Suppurativa, an extremely hypersensitive gastrocolic reflex, incredibly painful, frequent, and highly acidic diarrhea, and the chemical burns around my rear that have resulted from the increased level of hydrochloric acid in my bowel. The pain is chronic, and intense. My doctors are generally pretty dismissive, lumping my symptoms into 'general discomfort' and in the past even having labeled me as drug seeking. I pass food I've eaten withing 2 hours, in states that look significantly undigested, and sometimes my bones/ joints are so weak or swollen I can't move on my own. I also often lose control over the muscles in my rectum and become incontinent. Deeply embarrassing for a woman in her 30s.
I went to medical school young to try to diagnose myself, and while I was unable to finish, I learned a lot. I believe my current most pressing symptoms are the result of my surgery, not my condition. I'm currently taking painkillers, antispasmodics, proton pump inhibitors, and an ulcer medicine designed to coat my intestines and reduce the acid damage when I use the bathroom.
I already closely monitor my diet, in fact I can barely eat but once a day. I see my doctors far too often, and feel they're sick of my complaints. My insurance refuses many of the treatments they've tried.
What could help with the side effects of the surgery?
