I'm sorry to hear about your ailments. Of course it is impossible to determine if bankruptcy is your best option online, and even if it were possible it would be unlawful to do so in this forum for a host of professional responsibility rules.
However, bankruptcy might be a good option, it generally allows a person to discharge (wipe out) their unsecured debt, like credit cards, medical bills, personal loans, etc, and reaffirm debts they want to keep, like a mortgage. So, it may be possible to file Chapter 7 and get rid of all your debts except your mortgage.
I suggest you consult with a bankruptcy attorney in your area. Many of them offer free consultations, so you have nothing to lose and you may gain some very valuable information. I have helped a lot of people in situations similar to your with bankruptcy, and sometimes I have been able to find non-bankruptcy alternatives for them.
I hope this helps and a positive feedback is always appreciated if this was useful to you.
