How Do You Feel? (bad vs. badly)

                   
                           Right                                                      Wrong

 I feel BAD about your accident. (sorry)       I feel BADLY about your accident.

If you tell others that you feel bad, they will think you are sorry, ill, or sad, but if you say you feel badly, they could think that the nerve endings in your skin are inoperative, causing numbness. The word "badly" describes the manner in which something is done, and it doesn't usually follow the verb "feel."
