I understand that you don't have health insurance, but you need medical care. There are herbal remedies you can try, but it will be difficult to pinpoint exactly the ones you need if you don't know what parasite you have (or even if you have parasites at all.) Certain antibiotics will target certain parasites, but you need to know what kinds of parasites you have. If your hair is falling out, you have severe nutritional deficiencies, probably iron, or Vitamin B/magnesium. You should never take iron tablets without getting your levels measured first though, because too much iron can be fatal. I really would look into getting insurance either paying for it monthly, or getting a job that offers it. Money is no object when it comes to your life/health.
