I only write free verse poems cause I dislike following an order xD. Your feelings shouldn't be bound by a number of lines, stanzas, and rhymes ^^. I'm more likely to write a tragic ending than a happy one (I enjoy tragic endings xD).
In my story "Will you come and thank me, When the world ends?", every line in the poem is a manifestation of Hachimi's Feelings, not mine. I only write what the character feels about being bound in a perfect place.
What would you feel if you became your perfect self? will you be truly happy?
