Hi, Welcome to Health care magic forum.
As you describe, it appears that you are deficient of blood, and B complex, and must have worms in the intestine.
The infestation, make you deficient of blood and
vitamins.This condition makes you to eat the other things like, slate pencils,chack, or raw rice, or even clay, soap, etc.
I advise you to consult a physician for diagnosis and treatment .
I usually prescribe to my patient with such symptoms
albendazole, iron preparations, multivitamins, etc.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods.
Wishing for a quick and complete recovery. Thank you.
