With a pitch-black sense of humour, If You Feel Terrible is the first poem from the book Terror, Terrible, Terrific by US poet Rebecca Wadlinger. A bio:

Rebecca Wadlinger was born in Pennsylvania, where she attended the Stadler Center for Poetry at Bucknell University. She received her MFA from the Michener Center for Writers in Austin, and her doctorate in Literature and Creative Writing from the University of Houston. Her poetry has appeared in publications like The Best New Poets anthology, Tin House, Ploughshares, and Mid-American Review, among others. (source)

This film of the poem is directed, illustrated, and animated by Nick Stokes.

I found the film in Judy Elfferich‘s outstanding Poetry in Motion section of the Dutch website ooteoote, where she has been publishing videopoetry since 2015.
