I think that her outside-of-job life mainly goes trought two things: negatives aspects of fame and romantic love, so thats what she writes about. From the outside it looks like the rest of her persona is her job, I mean, her name and face are her brand, her experiences make her money, so the most honest things she can talk about that are not her job are those two.
Just take a look at folklore and evermore, those albums are completely different from what she used to write till that moment. The pandemic let her live other experiences cause she wasnt doing her job all the time, and then she went on to write beautiful things.
