It sounds like you're having a really tough time. Have you tried re-balancing your body's chemistry? Over at the "Ask Moreless Alkalizing forum" he gives a lot of easy to follow advise on how to get started.
Most of his "recipes" are inexpensive, and replace much pricier options.
Lots of water with lemon and himalayan or celtic Sea Salt , and fresh greens with plenty of [chlorophyll and] nutrients and taking probiotics internally, may be a few things to get started with along with that line as well.
Also, colon cleanse, sweating, and detox baths might help your body to get back to normal functionig.
What we eat and drink really has such an effect in our bodies. We put gas in our cars because that's what they run on. Yet we put garbage in our body, and expect it to work perfectly well.
You will find recipes for all these different possibilities over at the Moreless forum, posted by him, and numerous other very knowledgeable people.
And Invincible has gathered some of the most important posts, and put them in her "Alkalizing my way to health" blog... mind boggling.
