Federal law prohibits "discrimination" based on the filing of bankruptcy. I had posted a link to the law on here several months or a year ago. Basically what the law states is an employer can not take negative employment action on you or your application file based solely on you filing for bankruptcy. It is covered in Title 11 sec. 525. For the agencies that do, this is one law the government did not excuse themselves from and the agencies are putting themselves at risk of a lawsuit, especially if the fact is written.
With that said, I would probably make sure I had the receipts (or bills) for you medical issue. It would provide further proof that you filed because you were overwhelmed from medical bills. You can be disqualified for your financial actions leading up to the bankruptcy and financial actions since filing. As other have said you must be able to demonstrate you have learned your lesson. So don't let your appendix rupture again. Since it's not there anymore I'm sure you won't let it happen.
But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security.
Translation for the intellectually challenged: If the government screws the people too much, it is the right and duty of the people to revolt and form a new government.
