medical bills and student loans

I worked 80-90 hours a week for 9 years. It was horrible. I was miserable. Just a few weeks ago ago i was finally able to pay off enough of my wife's student loans that i could afford to start working a bit less & staying home more. And then on Friday i received these. $6,709 in medical bills. I'm so sick and tired of working so much and sleeping so little. Starting tonight i'm going back to working 80-90 hours a week until i pay these off.  I just want to be home to spend time  with my family. I'm so sick of this.
