OMG. Don't listen to anybody here. Get to a qualified nutritionalist and gut specialist. You sound malnourished, badly. But these people, myself included, are mostly a bunch of bored armchair experts. You need somebody to take a physical look at you. Your symptoms could be anything from a tapeworm to a B12 deficiency, and it takes labs to figure that out. Don't listen to us, man. You have very real problems!
