I was so sad when I read your post. I can only imagine how horrible your life has been.
For the most past, you have treated this topically. Why not try treating it from the inside?
Your body sounds like it's full of toxins. It needs to be cleansed. Dr. Clark (located on the homepage) lists all the cleansings you can do. You should complete several liver/gallbladder flushes and a Colon Cleanse for sure. I would also recommend a parasite flush.
