You need work but you got potential for sure, I'll give you constructive feedback, no hate, just trying to help...

The best aspect of your poem is the emotion without a doubt but your imagery and overall poetic vibe needs a bit of work. Vocab might be improved but big vocab is not necessary to write an excellent poem. Just try to use a lot of images, pictures through which you express your emotion. Might put some nice sound expressions in it such as internal rhyming, alliterations and assonances. But your emotion was excellent already, just work from there and you'll become damn good poet!
