Sam M's "Worth it" is about staying devoted to someone who hurts you. The speaker opens by saying he isn't worth the tears, sadness or pain, yet admits he is "your everything." That contradiction drives the whole poem. Speaking in the second person, the voice seems to be talking to itself, as if the speaker can only face these feelings by putting a little distance between herself and them.
The feelings are heavy: hurt, self-blame and shame. The speaker hides her tears, pretends nothing happened, and agrees that everything is her fault. Lines like "You're a screw up" and "Stop being a burden" show how thoroughly she has absorbed his criticism. Friends tell her to give up, but she keeps going. The mood is quiet, sad and resigned. The repeated image of wiping tears away and pretending ends the poem on a hollow note: "It's better this way" sounds less like comfort than like a lie she has learned to tell.
