I don't know the story, how she knows you are on meds and what the episode involved, etc. but I would just take it as concern, smile and tell her yes or no, whatever it is. If you have an opportunity to educate her some on your type of condition, it might be a good time, you might be able to help others she supervises in the future that have that condition or other supervisors she knows and talks with, she can give them "good" information or correct their ignorance, etc.
