how do i know which legal topic to select.

I am sorry to hear about your bad experience.   Most states have very strict requirements regarding medical malpractice cases and make it very difficult to sue a doctor or hospital.  You must show that the standard of care was violated that that caused you severe damages.  If your damages are minor, then it is likely something that would not be practical for a medical malpractice suit.  This is because of the difficulty as well as the costs and time it takes to litigate a medical malpractice case.   However, regarding the issue of paperwork and other information being disclosed to others, you might want to look into a HIPPA violation complaint.  Please see this link for more information:   http://www.hhs.gov/ocr/privacy/hipaa/complaints/ Best of luck!
