Medication, in this poem, is both a literal and a figurative idea. At first the speaker uses it as a metaphor for needing something stronger than "i love you's" to feel okay. A boy, "he," becomes a kind of new medicine, but a small dose of his caring leads to an overdose, and the speaker is left worse off. The poem then lists what is slipping away: bright eyes, a loud laugh, good grades, regular meals.
Midway, the tone shifts from craving to admission. The speaker says she is failing and needs help, and that others are now getting it for her. She admits to being scared, but more afraid of where her life is heading. The ending reads like a plea, almost an instruction to whoever reads it: talk to the counselor. The mood is heavy and exhausted, yet quietly hopeful, since the poem itself is an attempt to ask for help and to feel "okay again."
