Here, the speaker's feelings are treated like characters, and the title "Roles Switched" hints at why. The first stanza shows the good emotions in bad shape: Courage is cowed, Composure gives way to panic, Love is hurt and confused, and Compassion meets scorn. The speaker seems to have been lied to and betrayed, and the qualities usually seen as strengths are the ones left shaking.
The second stanza turns to the emotions we normally dislike, and they come across as unexpected helpers. Distrust is annoying but protective, Fear holds the speaker's hand and keeps them safe, Jealousy pushes them to do better, and Gloom, though heavy, makes the flowers look more vivid. The "switch" seems to be that the friendly feelings fail while the unpleasant ones step up. The mood moves from raw panic and hurt to a wry, hard-won acceptance, with a hint of bitterness underneath.
