I can always find a poem that can express my mood. I remember discovering science fiction poetry decades ago.
Poems are a lot like art. You have the classic poets/poems and then you have the street poets/slam types. They always sound angry. I prefer Charlotte Mew/Frost/cummings /Dickinson/etc.
Last month I read Walt Whitman's The Complete Collection.
Young people need to learn ways to express themselves, and poetry and prose is a great way to do that.

Poetry is one of the destinies of speech.... One would say that the poetic image, in its newness, opens a future to language.

From: La poétique de la rêverie (The Poetics of Reverie) (1960) -- Introduction, sect. 2

... he did emphasize that the power of the language is in the image, that it's important to avoid abstraction as much as possible. I agree with that, even though most of his poetics has ruined American poetry working from the sensibility of the Pound ethos, with the notable exception of T S Eliot, who in a sense might be considered British. Maybe Pound was trying to outdo the French symbolists in his overly dramatic wish to be different. Guy Davenport parses this problem out very well in explaining that the French don't take themselves too seriously, having more of a sense of play that doesn't overstay its welcome, so to speak. Americans, he says, take this stuff way too seriously. That was certainly true of Pound.
