You have a good thing going here, I just have two suggestions:
1. Write out the full words for "you" and "why", people will generally take your poem more seriously.
2. If you are writing a poem that you intend to have rhyme, as I assume you did with this one, try not to rhyme a word with itself. For example "you" with "you", which you did twice.
Other than those two things, I thought your poem was fairly nice, strong emotions, and you got your point across clearly. Good job.
