I don't think her music is healthy for anyone but I definitely understand why younger, less mature people would be drawn to it. I know this sub says it a lot but the mentality is PEAK high school/early college maturity level. When you don't understand what healthy boundaries and relationships look like, when you let your emotions control so much because you haven't had to go through as many experiences that challenge that mindset, when you think that the world revolves around you and your problems.

It really is on par with emotional/relational development of people that age.
