Where can I get afforable health insurance for a low income young adult?? please help?

With the new health care laws if you live in the US you can be added to your parents insurance until age 26. This will probably be your best and cheapest insurance. If it has been over 60 days since you dropped your insurance then COBRA (govt plan guaranteed to allow no preexisting condition which you now have) is not available. Some states do have a insurance pool. You may also qualify for medicaid. Your local hospital will have a financial aid area that can get you the info for that.
