Why does Abigail Adams describe herself as feeling cheerful and lighthearted in the March 31st

section of her "Letter to John Adams"?

In her March 31st "Letter to John Adams," Abigail Adams feels cheerful and lighthearted due to her belief that with the development of the newfound United States, woman have a chance of being formally recognized and empowered (politically, socially, and economically) by the new government. She feels a sense of hope for all the free people of the new United States, an emotion she did not feel - as she notes in her letter - during the previous year.
