I dunno if this helps, but I know you can make payments on those if you can't afford it all at once. I know my one neighbor sorta always has hospital bills nd she just doesn't have the money to pay it (no insurance) so it just takes her forever to pay them off, but so long as you make payments I think you'll be fine? THough not sure how that stuff affects your credit score.
SO yeah be sure to check your options. I'm sure you can call about it to see what can be done. :)
