PLEASE HELP! What are some examples of figurative language in the book Five Feet Apart?

What is implied in this sentence from mark twain's "the £1,000,000 bank-note"? i was puzzled, and wanted to discuss the matter a little further, but they didn't; so i took my leave, feeling hurt and insulted to be made the butt of what was apparently some kind of a practical joke, and yet obliged to put up with it, not being in circumstances to resent affronts from rich and strong folk.

In the poem i felt a funeral, in my brain what rhyme scheme does the poet use and how does it contribute to the poem?

How is dr. lanyon characterized in the excerpt? as friendly as arrogant as wise as mournful
