I need help bad.

I just had surgery that will keep me out of work at least another 5 months, I have been out for 2 already. I have atleast 3 debt places after me for medical bills from years ago. I support a family of 5 alone. I have my fiance, and 3 kids ages 5, 3, and 4 months old. I need to be able to pay my immediate bills, while trying to take care of this debt. Its difficult to do.
