I feel like it's about someone close to her--her mother, perhaps, as others have suggested--who has a lot of problems that end up hurting her. For example, say the mother was abused as a child and never got the support/help that she needed. Throughout her life it still affects her, and she endures other hardships as time wears as. Because of her problems, she inadvertently isn't a very strong parent, and the child suffers from both watching the mother's state and also from receiving neglect.

At least, that's one possibility.
