I think she's an INFJ. She is altruistic, wants to do what is good for others and make them happy, but does not take care of herself. She is responsible and obedient to her parents (Fe) and concerned Von social expectations. She builds her self-esteem from what others think about her(Fe). She is incredibly creative and artistic(Ni-Se). She builds a original and beautiful castle, and a gorgeous ice-dress.
