I had an overdose of antibiotics (after too many vaccines) and I ended up with a ton of sensitivities... And already had parasites and metals. It really messes up the body.

I'm sorry that you have been so ill. Please keep trying! I have healed from Chronic Fatigue and I have nearly healed from lymphedema. There is hope, and I am pulling for you!
Great Plains Lab has the Organic Acid Test which would cover a lot. Check their website.
www.greatplainslaboratory.com/home/eng/full_oat.asp. The website has info on how to get tests covered by insurance, too, and free webinars. You can call and ask questions if you want to talk to a live person.

For now while you have trouble digesting foods, you may want to try Nutriiveda, the original formula. Check the website and you will see what I mean... Many testimonies from people with severe illnesses who ARE able to digest it. It is currently being studied because it has helped to cure kids with apraxia, and has even eliminated seizures in some people. Basically it will gently detox while it nourishes from what I understand. I have used it. Pricey, but good nutrition AND it would gently help your body detox.

Find a local osteopath to help your body get back into balance and start healing. That should also be covered by insurance.
I have much more to share, but I will post later or you can contact me on this site.
