How to heal?

I think the bulk of my issues stem from my gut. After seeing doctor after doctor I made my issues worse. And after trying to take it in my own hands I'm became even worse. Dropping foods for relief. Most of my issues were insomnia, severe anxiety burning skin, diahrea. I've been stuck eating the same foods. So far tests have shown, I am low vitamin d, e, k and calcium. Higher in chloride. Oat test show i may have candida and alot of oxalates. Im sensitve to salycates as well. And my environmental allergens are overloading me as i allergic to alot. High calprotectin. My stools are light colored. I have had a gastric work up and only found high smooth muscle antibody test. My symptoms are worse during menstratuon and ovulation. When I try to introduce a supplements my body reacts. Extreme fatigue, anxiwty or insomnia. Things I've tried Magnesium chloride: anxiety Magnesium sulfate: hypnic jerks, feeling drugged Magesium glycinate : insomnia Magnesium citrate: anxiety and little twitches all over. Vitamin d Vitamin e Cromolyn sodium : burning skin increased, reacted to water, felt like i had acid in my muscles and jerking Antihistamines: extreme anxiety and panic Pepcid: dropped my blood pressure and had palpitations. Did notice a mental calm Ginger: panic, insomnia I would also like to add that i have gone through benzo withdrawals. Doctors took me off way to fast. I also needed up in the ER after a mix of trazodone and another antidepressant. I think seratonin syndrome.
How do I heal if I react to the very things that can help me. Has anyone experienced this? What helped you to heal? What steps and what order. I'm so lost. I've been going through this for over 2 years.
