Hamlet expresses his melancholy in several ways in this soliloquy. Start at the beginning: he wishes that his flesh would "melt." Then jump to the end: he says he's so upset over his mother's actions that his heart will break. In between, several points indicate how upset he is. Crying out exclamations like " Fie on't! ah fie!" give a good sense of his emotional state. The other ways he indicates his upset is through the words used to describe his mother, and through his references to the mythical woman Niobe, whose pride cost her her children.
