Good morning!
You have a very powerful poem here; it is very descriptive and emotional. A lot of unexpressed fear comes through your stanzas.
I'm not really sure if the stanzas meet your instructor's requirements though; I believe you have captured the five senses adequately, but I do not see the simile or metaphor component that you specify is required.
A simile is comparing two things using "like" or "as", and a metaphor is symbolically replacing one item with another unlike item. So, you could
use the simile in stanza 3; "Knowing I couldn't help them was worse/Like being a helpless bystander/So I stopped and thought...". Then you could use the metaphor in stanza 5; "Sufferings I heard they had been through/That I would soon go through/Understanding and appreciation a murky puddle about to become crystal/To get out of this nightmare...".
Or, you could rewrite and spend one entire stanza on the simile, and another entire stanza on the metaphor; whichever you find more appropriate.
Good work!
