Unfortunately I doubt there's a one-stop solution to this problem. Allow me to throw in my two cents. First off I would like to recommend a little reading:

http://educate-yourself.org/ozone/

I posted them off the same site for a reason, a lot of good information there, but it's only a start. To me, it sounds like you may possibly have an oxygen deficiency. Your body can't use any of the nutrients you throw at it, because your cells may be lacking the oxygen content to use those nutrients. Another possible step in the right direction could be radionics therapy, although it will be a bit more involved than what I posted above. Hydrogen peroxide and apple cider vinegar, when ingested, will promote balanced PH (in the human body this is slightly alkaline or high PH). However, I will stress following the guidelines for hydrogen peroxide therapy if you have never tried it. Oxygen therapy, of which, one possible method of delivery is ozone, also helps balance PH. Balancing your PH is incredibly helpful with all of today's acid inducing products.
Even some "natural" products these days are not so natural, e.g. Genetically-Modified-Organisms products and aspartame. Stay away from both at all costs. Aspartame may be labeled under natural/articifial flavoring or spices, or in the case of the newest neotame products, not at all. Your best bet is to not buy anything that has a label, unfortunately. Fresh fruits and vegetables only. If you decide to try either of the above "cures".. If you can even call them that these days without getting in trouble. You may want to attempt to limit your food intake to smoothies and vegetable juice. When I first started with them, they didn't taste very good. Once your body can flush out toxins, you won't crave the "junk" as much. Soon, those cravings will all but disappear and fresh foods will taste 100x better.
Other potentially helpful things may be orgone chargers or Colloidal Silver . An orgone charger can be easily built at home. Simply layer organic and inorganic materials together and it will do all the work for you. Simple solution, make a blanket with alternating layers of cotton and steel wool. It will be cumbersome, but 20 mins in the morning and 20 mintues at night should help. Should you overcharge, the best solution is a shower. Water molecules are the best thing none for grabbing the orgone charge (soft electrons). As a quick note, never use aluminum for healing. It will not work, it will make things worse. Steel/copper are your best (cheapest) bets for healing. Colloidal Silver on the other hand is the miracle antibiotic. It will kill anything from bacteria to viruses any and every time, no more guessing with Antibiotics . The best and long term cheapest solution is to get a Colloidal Silver generator online. I like to do a sinus rinse with it when I am sick. It works extremely well. The one and only possible side effect to it is argyria, but as long as you don't take substantially too much. You won't turn blue.

Any how, after re-reading this. I feel like I'm selling a product. Take this as a bit of information. I am not trying to push a product. These are just things that I believe could help. Hope the best for you.
