I have little advice to offer since I am having so many issues myself with both leaky gut and candida, adrenal, anxiety, food reactions . You can look at the whole approach website for a lot of information. They have a diet that you can follow and print out. Also, there is a forum that you can ask questions and get advice.
I am so sorry for what you are going through. Even though my family believes me, I feel really alone because I'm dealing with so many extreme issues and I'm really not sure that I can get better for various reasons which I won't get into. It must be so difficult for you not to have any support while physically feeling awful. Just know there are people out there like me that are thinking and praying for you and all of the other sufferers out there.
