those numbers sound awfully high for someone without an income. perhaps it's your previous income that's being taken into consideration. in any event i suggest you call the 800 number on your state's exchange to get help walking through the process. without an income you should qualify for a plan with much lower monthly costs and/or medicaid.
i don't have an income at the moment. . however the price quotes for the various health insurance plans don't seem to take that into consideration. the "affordable" healthcare is giving me prices of about $460 to $860 per month for just the silver plans.
