You are getting too many inputs and can’t possibly follow all of them. Simplify what you are doing and stick with it for several months and see what happens. You might want to keep a food journal of what you eat and drink and symptoms as they happen.
Get yourself tested for celiac disease which is a disease that causes malabsorption of different nutrients depending on the individual. It is a blood test and maybe and endoscopy.

I have also been having a lot of health problems especially in the past year. Doctors were not giving me answers. It was suggested that I contact an Amish Healer by the name of Solomen Wickey in Auburn, IN. He diagnoses you by looking at your eyes, so I sent him a picture of my eyes. He wrote me back immeditaly and told me that I have an Candida Yeast infection. His diet suggests that you stay away from sugar and white flours, you are allowed whole grain, unprocessed meats and fresh vegatables and fruit. He suggested a antifungal herb treatment called Can-Sol and Acidoliphis pills taken for two weeks and stay on the diet for two weeks. This is my third day and believe it or not I’m already feeling better. People from all over the world seek this guy out for medical help, he seems really amazing at what he does. His address is 6308 Co Rd 43, Auburn, IN 46706. Its worth a shot, he doesn’t charge for his diagnoses only for any treatment you need. I thought I was going crazy too before I got an answer from WIckey. I don’t trust doctors at all anymore. Good Luck, I hope you find an answer.
