This is a good piece of writing : )
you seem to be loaded with feelings to express, yet no one can easily find the right words to do so
am not an expert writer myself but I know that what weakens a poem is the ordinary choice of words, you should look for new vocab and never hesitate to use them
I think in the third stanza it's better to say :
"I'm still wondering,
why aren't here with me ?
I can't hear you,
Can't see"
and you should replace "your" by "you're" throughout the poem
