Mary is constantly complaining of being ill and indisposed. What exactly would she be ill with to the point she could get away with complaining of it so much?

I heard somewhere that while ladies had their periods, if they wished to avoid company during this time, they would say they were indisposed, a term Mary uses frequently. Given the lack of medication for irregular periods, heavy bleeding and period pain, not to mention sanitary products, your period would be a trial if you were good natured, yet alone if you were Mary!

However, I refuse to believe that her menstrual cycle could be bothering Mary all the time!

Perhaps she had a mild form of depression too. She always complains of fatigue, a common symptom of depression, and seems to be paranoid about neglect, and experiences general doldrums.
