You will most probably qualify for subsidies that will mean you pay little, if anything or qualify for Medicaid. If you make below a certain amount and Medicaid isn't being expanded in your state then you're exempt from buying it
Go to http://www.thehealthsherpa.com and you will find an estimator. Plug in your zip, and the plans pop up. Plug in your annual income, and subsidies are applied. Then call the plan administrator you want and get the ball rolling. If you are at poverty income, Medicaid may be your avenue. If not, I will wager there will be some subsidies.
