I am a white 62 year old female who was fired by a black female for being rude to patients. Which in 7 years I have never been accused of.

Your race and the race of the person who terminated you are not legally imporant. What is important is the motive.  In otherwords, why were you fired? If you were fired due to your age or race, you may have a legal claim. If you strong evidence that age or race was the reason, then you may have a strong legal claim. There is a very short period for filing a legal claim on race or age so consult with an experienced employment attorney as soon as possible.
