Re: Some advice needed here..
Have you thought about a juice fast? This saved my life (along with many other things you're doing) when nothing else was working.
I would go on a freshly extracted vegetable juice fast, with plenty of carrots, beets, leafy greens, celery, lemons, and cruciferous vegetables. It costs time and money, but if you've tried everything and you still feel in a dead-end, this could very well get you well, and faster than you could imagine. You need to aim for a gallon of juices daily. Yes, a gallon.
If you can't afford the cost, you may choose to go on a liquid diet, with plenty of vegetable juices, the rest being smoothies made of homemade milk kefir or water kefir, mixed with vegetables or little fruits. Throw in some flaxseeds, coconut oil, superfoods...
