Y I don't understand what you're saying. Depression can be recovered over time, people don't always live with it their whole lives. That's an inaccurate statement because even war victims can recover. They may not be perfect, but they can recover. It does not always stay with people their whole lives.
Rosa I'd say no. Depression isn't really something you recover from, it's something you live with your whole life. At the end of the book Mia is learning to handle her depression and Marchetta gives us a optimistic ending that makes me think Mia might learn to live a semblance like her life before at some point.
