A metaphor is a direct comparison between two things. For instance, the expression "your words are music to my ears" is a metaphor comparing what someone has said to music. Now that you have that definition, reread the poem and see if you can find any lines where the speaker compares herself to something. (Hint: the only metaphor I can see is in the first few lines.)
Consonance is a form of alliteration in which consonant sounds are repeated in a line of poetry. For instance, "Peter Piper picked a peck of pickled peppers" is an example of consonance because the consonant "p" is used repetitively. The consonant doesn't necessarily have to be repeated as many times as the "p" is in the tongue twister. Look through the poem and try to find any lines in which a letter is repeated two or more times. (Hint: look at the first stanza.)
I'm sure you can find the answers yourself now.
