Ok, its an awesome start, but it needs work. I love the title, and how its like a letter, however its not a poem.
1. Don't mention "poem" in a poem... its tacky.
2. Its more of a rant, like a letter, than a poem. You can fix that in a few ways (I had this same problem)
----
You need to form a structure. There are so many types of poems, you dont need couplets or quad, or 6 like mine. It doesnt need to rhyme, or have many poetic provisions (such as alliteration, or metaphors) although I believe a good metaphor can make an entire poem.

I was also suggested to make it more active. I'm not sure if you know what that means, but that means removing personal pronouns such as I, me, you, etc. I realised that that is amazing, and it totally makes the poem soo mcuh better. It also challeneges the writer to find a backdoor to saying what is wanted to say.

Add a structure, make it active, less of a rant, and add some metaphors (love them!) and it will be a truly awesome poem
