I like this. Even though you haven't said you want critique can I give you just one suggestion?
Don't force yourself to rhyme. I think that in this poem, because the rhyming felt forced in some places, it took away from what you were trying to say through it. Maybe try this one again as a free verse.
That's just my suggestion.
Keep up the great work.
