What did daisy mean by the statement sophisticated god im so sophisticated at the beginning of the novel the great gatsby?

IN MY OPINION think about the context. She's thinking about the hopelessness of life for her, her new born baby. When she says "I hope she's a beautiful fool" she shows how hopeless she feels. She's spent so long traveling, transforming into this lady of high society. how sophisticated she is… how sophisticated. what i think she wanted to say is

My god,,,, what have i done… So sophisticated, so empty-
