I think she should just focus on the fact that she was lucky to be born in a family that is very privileged that they lived in actual castles and palaces, there are many people who had a far less privileged life but still managed to be grateful with what they had.
I agree! Maybe that’s what’s wrong with her. She doesn’t have the character to cope with her privilege.
I think ML just lacks character full stop.
If she had been born into deprived or regular middle-class circumstances she would still complain about her lot in life because lives a perpetual victim narrative.
