"No doctor can help you" is not entirely correct. Find a good functional medicine doctor who runs the right tests. You will be running around in CIRCLES trying new things without any scientific testing, knowledge or growth on your end. The first year of my illness I literally just tried every supplement, protocol, etc. and it was a disaster. I ended up knowing that it did not work but never had an explanation for why something had such an effect on my body. Thirst for knowledge and answers and you will find that certain doctors have lots of offer. Not many and definitely less than .01% of regular conventional doctors but those trained in funcntional medicine can help.
I suggest you to functional medicine institute on google and they have a directory. I have used this directory to much success. It helps if you find any other reviews on the doctors but sometimes it really is a crapshoot of someone good and someone mediocre. The worst that can happen is you get a cdsa and a stool test and some answers that you cannot find in conventional medicine.
