Victor's poem is about a kind of loneliness that can show up even when other people are right there. The speaker asks whether anyone else knows the feeling of sitting alone, or with a big group of friends, and still feeling cut off. Conversations seem to flow over them, so they go quiet or stare into space, thinking "what's the point."
The second half turns more painful. At home, the feeling hasn't gone away, and the speaker wants to cry but can't. Their eyes sting and look red, yet nothing comes. That numbness is what they call "the worst feeling," and it's easy to see why: sadness would at least be something to release, while emptiness has no way out.
The mood is flat, tired, and quietly desperate. The plain, unpolished language and the opening question make it feel like a real confession, as if the speaker is hoping someone will answer "yes, I know."
