This is one overt reference to balance in the play. Agnes says this line with an exaggerated tone, but I think this is only out of her comfortably with being all of these roles. Her character is the type to like holding countless titles and would mock anyone that cannot "balance" these things. Her fear of going mad does show some vulnerability regarding this balance that she maintains and aides in her momentary "would I be better off as a man?" thought. However, she soon talks herself into a realization that there is a balance that is maintained in being a man, as well. Agnes enjoys the balance she strikes up as a woman but fears the risk that comes with its delicacy.
