Start considering some diet changes, pronto. Look into the Alkaline Diet, as disease can only exist in acidic environments. It is simple, cheap, and the best thing you could possibly do for yourself and those you love.
In the meantime, since I see you're also in Minnesota, you can apply for MinnesotaCare, which is state-sponsored healthcare. If you do apply, which is a simple process, I recommend choosing BlueCross BlueShield as your provider option, since basically everyone accepts them.
I hope that helps, and good luck.
