Healthcare isn't an extra, its a necessity. Have you applied for medicare and or medicaid? That should be your next step if you want to seek professional treatment.
About the hospital bills, you should tell the hospital that you are unable to pay. You may be able to arrange a bill assessment (different places call it different things) where you can submit documentation showing your incomes and necessary bills (like rent and utilities) and if it shows thhat there is no way you could pay the amount you were charged, a lot of times they will reduce it to something more reasonable. They'd rather get something than nothing. Takes some effort on your part, but it could help you a lot. Otherwise you are likely to get sued and have your wages garnered. This could help you avoid that.
