You have to take care of yourself mentally though do you can get your life back on track. Once you do that, everything will work itself out! If you can accept that this may be what you have, you can work from there and things will improve, but you have to stick with it. Without an official diagnosis, I personally would have a harder time sticking to it since no one has actually told me I have it. You have to make the decision from the beginning that you aren't going to do that until you can get tested. It should be easier if you see improvements with the diet....... Oh and I would start with gluten first.... If you start getting rid of soy and diary and gluten all st once. You won't know what is actually doing the trick!
