Walking past a crowd that seems to be glaring at you is the whole situation here. The speaker feels stared at, and the stares are not friendly. The image of "raging fire in their eyes" makes the looks feel hostile and almost physical, as if they could burn. We never learn who "they" are or why they are staring, and that vagueness helps. It could be strangers, classmates, or just the speaker's own sense that everyone is watching.
The speaker's feelings are easy to follow: discomfort, anxiety, and the panic of "freak out." The short, plain lines make the poem sound like a thought blurted out in the moment, a bit breathless and tense. The ending shifts from fear to longing. The speaker doesn't want to feel this way and wants to feel like themselves "every day." The mood is uneasy and self-conscious, but there is also a quiet wish for freedom, for being able to walk through the world without being judged.
