Mirth Book 2 Parts IX and X

Lily Bart from The House of Mirth is becoming much more troubled now that she has stooped to the working class. The relationship between herself and Selden is oddly hostile, and for some reason Selden acts like he never left her alone when he took off for Europe. Plus, Lily acts affectionately with Rosedale. This has become a complete flip from the beginning of the story where Lily would've much rather been with Selden than Rosedale. Lily's character has definitely changed. Physically, she appears to be the same because even at this point in the story Rosedale admires her beauty: " ...Rosedale was seized afresh by the poignant surprise of her beauty (235)." However, Lily is emotionally distressed with her situation of going from a life of luxury to the life of a peasant. 

I think I know how this novel will end. Lily's conversation with the chemist I think is hinting at how the novel will end with Lily overdosing on the sleep medication and dying. I am still unsure whether it will be because she is so troubled about her situation, or it happens as an accident due to her sleeping difficulties. Nonetheless, I would rather just get to the end of this book.
