Her feeling sympathy for the rubbish because she views herself as the same, could include mental health issues or family troubles.
Is the boat turbulent ? Because you could say that she’s trying to pick up her life when everything else is against her.
Feeling like she’s making decisions too quickly because society is fixed in a certain way so picking up the rubbish(things she doesn’t really want in life).
Idk just a quick brainstorm hope it helped☺️
