It makes sense that most of her problems was not been resolved, and maybe those problems are emotional problems such as family problems that cannot easily be resolve.
In the poem there is someone besides her that tells some of his experience, but she just laugh about it. It can makes sense that he is somewhat very close to maningning because of being thought about an experience of him. But even the closes friend of her left her.
therefore, I think that maningning's life is not a happy life to be acknowledge. Besides she commit suicide.
