Truly I believe that most illness is due to what we eat - makes sense because we put food in our bodies 3 times a day - so if it is food, then the illness never ends, and when people fast, they often get better. There are even fasting clinics that treat all sorts of terrible diseases, and people improve. I read of a woman who was so arthritic, she could barely walk - gave up dairy and in a month there was nothing wrong with her.. my own son, once he was taken off sugar was a different child in one month. I could go on and on..
I'm sorry this is happening to you! I hope something I say will help.
Here's my suggestion - just as an experiment for a month (people say it only takes 2 days to see a difference), try eating only organic food - no GMO food (loaded with pesticides), nothing processed unless it is organic.
I know this is expensive (but actually, it isn't that much more), and we are talking about your health here!
So, breakfast could be organic eggs and fruit (you can buy these in most ordinary grocery stores), lunch could be organic meat, veggies, rice , yogurt and fruit.. keep your diet real simple and I honestly believe this will help.
